What is the percentage composition of C14H20N2SO4?
Here we go: C14H20N2SO4 has 14 carbons, 20 hydrogens, 2 nitrogens, 1 sulfur, and 4 oxygens. (That's penicillin, by the way.) The molar mass is the total mass of all the atoms, which works out to be 312g/mol. Now, just get part divided by total for each: Carbon: 12x14=168, 168/312=0.54=54% Hydrogen: 1x20=20, 20/312=0.06=6% Nitrogen: 14x2=28, 28/312=0.09=9% Sulfur: 32x1=32, 32/312=0.1=10% Oxygen: 16x4=64, 64/312=0.21=21% *(just make sure your percents all add up to 100!)

How many atoms are found in 600 grams of iron?
To find the number of atoms we need to find number of moles of Fe in 312.0 grams. Molar weight of Fe = 56 Number of moles of Fe in 312 grams = 312/56 =5.571 moles. 1 mole of Fe has Avogadro number of atoms. So 5.571 moles of Fe has atoms = 5.571 * Avogadro number. Avogadro number = 6.022 * 10^23 So total atoms = 5.571 * 6.022 * 10^23 = 33.548 * 10^23 * means multiply, ^ means raised to power.
