Article: To calculate mass from volume, you must know the density of the object. Different materials have different densities. Consider a sphere made of styrofoam, for example, and compare its weight to a sphere the same size made of iron. Iron has a much greater density and will therefore have a greater mass. You can find densities of many solid materials by looking up density tables online, in textbooks or in other industry catalogs. For example, here are the recorded densities of some solid materials: Aluminum = 2700 kg/m3 Butter = 870 kg/m3 Lead = 11,350 kg/m3 Pressed wood = 190 kg/m3 The units you used in calculating volume must match the volume units in the density measurement. If they do not, then you must convert them. All of the examples in the previous section resulted in volumes measured in cubic centimeters. However, the cited density table provides densities based on cubic meters. Because there are 100 centimeters in a meter, there are 106 cubic centimeters in a cubic meter. Divide the given densities by 106 to represent the density in units of kg/cm3. (You can do this most easily by just moving the decimal point 6 spaces to the left.) For the four sample materials, the converted densities are as follows: Aluminum = 2700 kg/m3 = 0.0027 kg/cm3 Butter = 870 kg/m3 = 0.00087 kg/cm3 Lead = 11,350 kg/m3 = 0.01135 kg/cm3 Pressed wood = 190 kg/m3 = 0.00019 kg/cm3 Recall that the formula for density is Density=MassVolume{\displaystyle { ext{Density}}={
rac { ext{Mass}}{ ext{Volume}}}}. Rearranging this to find the mass, the equation becomes DensityVolume=Mass{\displaystyle { ext{Density}}*{ ext{Volume}}={ ext{Mass}}}. Using the four sample materials, aluminum, butter, lead and pressed wood, find the mass of a sphere that has a volume of 500 cm3.

Question: What is a summary of what this article is about?
Find the density. Convert the units as needed. Multiply volume by density to find mass.

Problem: Article: Many people take insurance for granted, but if they see danger or potential hazard in their future, they're more likely to consider buying insurance. Insurance doesn't even have to be mentioned. They should be prompted with a question related to their situation, as well as the insurance you're attempting to sell. Potential house insurance questions: What's the most valuable thing you have in your house? Have the recent floods been anywhere near your house? Potential life insurance questions: How long do you think your savings would work for your family if you passed? Are you aware funerals can cost nearly $10,000?! Potential disability insurance questions: Could you continue your physically demanding job if you were permanently injured? If you get injured and can't work for a long period of time, can your spouse's salary support you? View things from their perspective to understand their problems and deliver possible solutions. Unique insurance ideas targeted directly at your customers' needs shows your passion for learning about them. Being their friends could help lead to a more lucrative connection. Did your clients just have a child for whom they might want life insurance? Have they recently thought about a travel trailer or camper? Are they really into boats and jet-skis? If so, you could insure the vehicles as well as review some health insurance options. Re-examine their coverage and use this as an opportunity to up-sell. You may find new reasons they are unsatisfied with current coverage, or ways to combine coverage currently not under your purview. Some companies also offer a multi-line discount, so this is another topic to discuss with your clients.
Summary: Ask questions that make people think about insurance. Learn personal details about your clients. Schedule an annual meeting with your current customer base.

Sometimes you can earn your bachelor's in biochemistry, but not all 4-year colleges and universities offer these specialized degrees. Take advanced courses beyond the minimum needed for the degree and major. You will do yourself a huge favor by getting a head start and learning things you will eventually need to know sooner rather than later. If biochemistry isn't offered at your university, aim for a degree in biology, chemistry, or physics. Make sure to take classes like General Chemistry, General Physics, Introduction to Biology, Introduction to Environmental Science, Anatomy and Physiology, Microbiology, Biochemistry, and Organic Chemistry. Much of the work you'll do as a biochemist will involve doing some type of research in a lab, so it's a good idea to get some experience early on if possible. Find out if your university allows undergrads to be employed as student laboratory assistants. Being a lab assistant will look great on your resume and will work in your favor when you are applying to graduate programs. Doing research early is critical to ensure career satisfaction, as research is a core component of being a biochemist. Moreover, research experience will greatly increase your chances of acceptance into graduate schools. Seek out senior biochemistry professors and express your career interest and desire to do research. It helps to take a look at their CV and research interests before you speak with them. Ask them if they have any opportunities available for you to work with them. While you are taking science courses and working toward your undergraduate degree, you also need to be gaining experience in the field of biochemistry. One of the best ways to do so is to apply for summer internships, work study programs for students in the Science department, or any other kind of job that will get you some experience to put on your CV.
