There are quite a few pieces of information we can glean from a chemical formula. The first is the mass of that formula. In looking at the periodic table, we know that each element has its own mass. When we combine that information with how we interpret how many of each element there is in the formula that we just went over, we can calculate the mass of the compound. Using glucose as an example:
C6H12O6 tells us that glucose has 6 carbons, 12 hydrogens and 6 oxygens. On the periodic table, carbon has a mass of 12 g, hydrogen has a mass of 1 g, and oxygen has a mass of 16 g (I've rounded for ease. There will be times you use the entire mass provided on the table and times you won't -you'll know when).
C = 6 x 12g = 72g
H = 12 X 1g = 12 g
O = 6 X 16g = 96g
Add these values together and you get 180 g so glucose has a mass of 180 g.
Calculate the mass of H2SO4.
Consider a mixture of 10 billion O2 molecules and 10 billion H2 molecules. In what way is this mixture similar to a sample containing 10 billion hydrogen peroxide (H2O2) molecules? In what way is it different?
Magnesium exists in nature as three stable isotopes. Suppose you determine that 9.87 moles of natural magnesium are required if you wish to isolate 1.00 mole of pure Mg-25 (24.9858 amu). The most abundant isotope is Mg-24 with a mass of 23.9850 amu. Determine how many grams of the third isotope, Mg-26 (25.9826 amu), can be isolated from the 9.87 mole sample of natural magnesium.
How do you solve this?
