CAN SOMEONE SHOW ME HOW TO DO THESE PROBLEMS?

A sample of H2SO4 contains 2.02 g of hydrogen, 32.07 g of sulfur, and 64.00 g of oxygen. How many grams of sulfur and grams of oxygen are present in a second sample of H2SO4 containing 8.78 g of hydrogen?

Mass of Sulfer = ____ g

Mass of Oxygen = _____ g

2. Two elements, R and Q , combine to form two binary compounds. In the first compound, 18.5 g of R combines with 3.00 g of Q . In the second compound, 7.00 g of R combines with 4.50 g of Q . Show that these data are in accord with the law of multiple proportions. If the formula of the second compound is RQ , what is the formula of the first compound?

Compund I: _____

3. In a combustion reaction, 49.0 g of hydrocarbon reacts with 96.0 g of oxygen to produce water and carbon dioxide. If 57.7 g of water is produced, how much carbon dioxide is produced?

Mass= ______g
