Find the concentration of the acid solution on the label, or in the word problem you are working on. This number is often written in units of molarity, or molar concentration, abbreviated as M. For example, a "6M" acid contains six moles of acid molecules per liter. We'll call this starting concentration C1. The formula below will also use the term V1. This is the volume of the acid we will be adding to water. We probably won't use the entire bottle of acid, though, so we don't know what this number is yet. The desired concentration and volume of acid is typically determined by a school assignment or by the requirements of the laboratory you are working in. For example, we might want to dilute our acid to a concentration of 2M, and need 0.5 liters (0.1USgal). We'll call this desired concentration C2 and the desired volume V2. If you are using unusual units, convert them all to units of molar concentration (moles per liter) and liters before you continue. If you are not certain what concentration or volume of acid is required, consult your teacher, a chemist, or an expert in the task you plan to use acid in. Whenever you prepare to dilute a solution, you can use the formula C1V1 = C2V2. words, this means "the initial solution's concentration x its volume = the diluted solutions' concentration x its volume." We know this is true because concentration x volume = the total amount of acid, and the total amount of acid will remain the same as it is added to the water. In our example, we can write this formula (6M)(V1)=(2M)(0.5L). This term, V1, will tell us how much of the initial acid solution we need to add to water in order to end up with the desired concentration and volume. Rearrange the formula as V1=(C2V2)/(C1), then plug in the numbers you know. In our example, we would end up with V1=((2M)(0.5L))/(6M)=16 liter (0.0USgal). This approximately equals 0.167 liters (0.0USgal), or 167 milliliters. Now that you now V1, the amount of acid you'll be using, and V2, the amount of solution you'll end up with, you can easily calculate how much water you need to make up the difference. V2- V1 = the volume of water required. In our case, we want to end up 0.5 liters (0.1USgal) and will be using 0.167 liters (0.0USgal) of acid. The amount of water we need = 0.5L - 0.167L = 0.333L, or 333 milliliters.

Silkscreens can only apply one color at a time, so create a simple shape or outline to begin learning. Whatever you draw will eventually be the inked part of the print. To make your own print, you need: Poster board, thin cardboard, or other thick & sturdy paper. Pencil X-acto knife or another precision knife Screen printing isn't difficult, as what you draw is exactly what you get on the final print. However, there are certain principles and limitations to screen printing that you should know as you design your print: You can only print 1 color at a time. High contrast images (like black on white) work the best, as you cannot use shading. For complex designs, you need to make multiple prints, one for each color, and layer them after the ink has dried. Sketch out the blocks of your design. You can upload photos or other images into photo editing software as well and use those. To do so, reduce the drawing to a basic two-tone outline then print it. To make a stencil on Photoshop, for example, you would take a black and white image and click Image Adjustments Threshold, then set it up near the highest it can be. Everything that you cut away will be un-inked on the final print, and everything covered by the stencil will be covered in ink. For example, imagine you are printing the red logo of a bulls-eye on a white t-shirt. When you cut out the stencil, all of the rings that you cut away will be white, and all of the rings that are covered by the stencil will be red. For complex prints, it can be very difficult to cut out the entire outline. In this case, use thick black ink on transparent paper to make your stencil. Your stencil or drawing needs to block light, as this is what etches the design into the screen and allows you to print. Everything covered by a stencil or black ink will not get exposed to light, leaving it "open" and allowing ink to pass onto the shirt or item.

If you just moved to town, you may not know the area well. Do some research to see if there were any recent tragedies or accidents. Some people believe areas that have dark histories are more prone to hauntings. You can look up the history of your town online. Try stopping by a local library that archives old newspapers. You may find some unusual stories there. Some websites allow you to enter your address and, for a fee, they will provide you with information about deaths that occurred in your home. You can also try simply searching for your address online. There may have been a news story if someone died in your home, or if a tragic event occurred there. You can hire professionals to do an energy audit of your home. This involves using a thermodynamic camera to check your home for dips in heat. A home with inexplicable dips in heat and uneven temperatures may be haunted. Energy audits can sometimes find logical causes of dips in energy. This can allow you to fix problems in your home that cause things like drafts, slamming windows, and flickering lights. Stick to people like professional mechanics, who offer non-paranormal services. Paranormal investigators are not legitimate and will not provide a real service. There's a good chance there's a rational reason for drafts and cold spots that may require repairs that paranormal investigators cannot provide. If you just moved to a neighborhood, your house may have a reputation for being haunted. Ask your neighbors if they know of any paranormal activities in your home. Ask them if previous neighbors ever said anything about your home being haunted.
