5x10-3 g divided by m.wt. of gold (197 g/mol) equals 2.5x10-5 mol gold.
2.5x10-5 mol gold multiplied by Avogadro's Number (6.023x10+23 atoms/mol) equals 1.5x10+20 atoms.

How many grams of sodium does a 5.35 g sample of sodium bromide contain?
All you really need here is a ratio of molar masses, ie molar mass of Na/molar mass of NaBr So look at your periodic table and is says: Na = 23g/mol Br = 80g/mol therefore NaBr = 103g/mol so from this, you actually know a percentage of Sodium to Bromine, correct me if I'm wrong, someone else please but just take: (23g/mol)/103g/mol = 22.3% of you NaBr is actually Na, so take 5.35g * 0.223 and you get: 1.19g of Na in your NaBr Hope that helps. Cheers

How much starch is in an egg?
Popcorn is produced from zea mays, a type of corn that has a thin enough outer hull to allow for the corn to pop when heated. Like other starchy vegetables, popcorn is a rich source of carbohydrates. Starches 101: Starches are a white chemical that all plants naturally produce. As a polysaccharide, starches, which are a type of carbohydrate, break down into glucose in the body, which provides fuel for your body's activities and is especially important for brain function. A 1-cup serving of popcorn has 6.2 grams of carbohydrate, which becomes glucose in your body after it is digested. Resistant Starch: Popcorn contains type one resistant starch, which is found in the cell walls of plants. It's present in seeds, beans and grains, including corn. As its name implies, resistant starch resists digestion, so it passes through to your gut primarily undigested, providing a source of nutrition for the healthy bacteria that lives in your digestive tract. In addition to providing fuel for your gut's bacteria, resistant starch may also help keep your insulin levels steady, reducing spikes in blood sugar.
