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.

The ratios in an equivalent ratio table are 312 416 and 520 If the first number in the ratio is 10 what is the second number?
To find the second number in an equivalent ratio table where the first number is 10, we can set up the ratios based on the provided values: 312, 416, and 520. The ratios can be simplified to fractions: ( \frac{312}{x} = \frac{10}{y} ). By finding the common factor and scaling down, we find that for the first ratio (312:416), the second number corresponding to 10 is 13.33. Thus, the second number is approximately 13.33.
