When 10.0g of calcium is react with 5.0g of oxygen, 15.0g of calcium oxide is produced. What mass of calcium oxide will be formed when 12.0g of calcium react with 6.0g of oxygen? Which law of chemical combination will govern your answer?

Answer:
%H=
mass compound
mass H
×100%
mass compound
mass C
×100%
If analysis of a 10.0-g sample of this gas showed it to contain 2.5 g H and 7.5 g C, the percent composition would be calculated to be 25% H and 75% C:
10.0g compound
2.5g H
×100%=25%
10.0g compound
7.5g C
×100%=75%
