Q: The average atomic mass tells you the relationship between mass and number of atoms in a typical sample of the element. This is useful in chemistry laboratories because it is almost impossible to count the number of atoms directly, but easy to measure mass. For example, you can weigh a sample of silver and predict that each 107.8677 amu of mass contains one silver atom. . Atomic mass units are very small, so chemists typically weigh samples in grams instead. Fortunately, these concepts are defined to make the conversion as easy as possible. Just multiply the average atomic mass by 1 g / mol (the molar mass constant) to get an answer in g / mol instead. For example, 107.8677 grams of silver contain one mole of silver atoms on average. Since a molecule is just a collection of atoms, you can add the masses of the atoms together to find the mass of the molecule. If you use the average atomic masses (instead of the mass of a specific isotope), the answer is the average mass of the molecule as found in a naturally occurring sample. Here's an example: A molecule of water has the chemical formula H2O, so it contains two hydrogen (H) atoms and one oxygen (O) atom. Hydrogen has an average atomic mass of 1.00794 amu. Oxygen atoms have an average mass of 15.9994 amu. The average mass of a molecule of H2O equals (1.00794)(2) + 15.9994 = 18.01528 amu, equivalent to 18.01528 g/mol.
A: Convert mass to number of atoms. Convert to molar mass Find average molecular mass.

Article: You can make it a relaxed part of your daily routine by doing it at the same time each day. In addition, you can make the time as enjoyable as possible by: Reading to the baby Singing Playing with special toys Putting on her favorite video Praising your child for having done a good job inhaling the medication This will give the child a sense of ownership over the nebulizer and make it seem less scary. Some children put stickers on the compressor. Your child can even pick out a mask that he likes. Possibilities include an elephant mask, a turtle mask, or a fish mask. You can also refer to it as a pilot mask or space mask and encourage your child to pretend to be a pilot or astronaut while inhaling the medication. Pacifier attachments are available for infants. The pacifier helps to soothe the infant while he wears the mask. This will give the baby a bad experience with the nebulizer which will make it harder in the future. In addition, a crying baby will not successfully inhale the medication. When a baby cries, she makes a very quick inhalation and a long exhalation. This means that almost none of the medication will be inhaled deeply enough to make into the lungs. If you cannot soothe your baby by holding her and singing to her, you may need to wait and try the nebulizer later when she is less fussy. However, if your baby is having trouble breathing and will not calm, you can use the nebulizer for rescue treatments if needed to help her breathe, even if she is crying. If your baby is a sound sleeper, you may be able to put the nebulizer on while she sleeps.
Question: What is a summary of what this article is about?
Stay with your baby while the nebulizer is on. Let the child personalize the nebulizer if he is old enough. Don't put the nebulizer on a crying baby.

Q: Make sure you do not walk faster than your customers. Walk slightly ahead of them, carrying menus and silverware to the table where you want them to sit. Ask if the table is okay before the customers sit down. Most customers expect to wait at least 10 minutes to be seated at a restaurant, especially if they didn't have a reservation. If your guests have waited much longer than that, offer a sincere apology as you show them to their table. Ask management if it's okay to comp them a free drink or appetizer (but don't offer it to the guests until you get permission). If the restaurant is slow, try to seat guests at a table that's not directly next to another full table. Of course, if the restaurant is very busy, guests will have to sit near other diners, but try to make sure all of your guests have enough space to be comfortable. By seating guests in rotating sections, you'll help ensure that all of your servers are able to make money for the night. Rotating stations will also help keep servers from becoming overwhelmed by getting several tables at the same time. You never want to throw all of the menus down on a table, as this seems rude and dismissive. Instead, carefully lay a menu and silverware at each place setting, and make sure your guests are seated before you leave the table. Be prepared to get water or other small items for guests. If they request more than that, politely let them know that their server will be right with them. You're the last person guests will have contact with, so offer a friendly farewell to guests as they walk out the door. This will help them leave feeling like they had a pleasant dining experience.
A:
Show your guests to their table. Apologize to your customers if they have had to wait long. Make sure your guests are seated comfortably. Rotate stations. Place a menu and silverware for each guest at their place setting. Speak to guests as they leave.
