How do you calculate the theoretical mass percentage of oxygen in potassium chlorate?
I believe it is: %O=mass of 3 mol of O / mass of 1 mol of potassium chlorate *100% If you measured it: %O=mass of oxygen lost / mass of potassium chlorate *100%
How do you calculate how many grams of water are produced from 22.1 grams of oxygen?
First find the percentage by mass of oxygen in water. The formula for water is H2O, showing that water contains two hydrogen atoms for every atom of oxygen. The gram atomic masses of hydrogen and oxygen are 1.00794 and 15.9994 respectively. Therefore, the percentage of oxygen in water is 100{15.9994/[15.9994 + 2(1.00794)]} or about 88.8 %, to the justified number of significant digits; the ratio of the maximum mass of water that can be made from a given mass of oxygen is 1/0.888 or about 1.126; and the answer to the question is this number multiplied by the stated mass of oxygen, or 24.9 grams, to the justified number of significant digits.
What is the percent composition of cesium in CsOH?
The given formula shows four atoms in one formula unit. Therefore, the atomic percentages are 25 % each of iron and oxygen and 50 % of hydrogen. The mass percentages may be calculated from the atomic percentages combined with the gram atomic mass of each element. These values are 1.00794 for hydrogen, 15.9994 for oxygen, and 55.847 for iron; this yields a gram formula mass of 73.857, to the justified number of significant digits. The mass percentage of iron is therefore 100(55.847/73.857) or 75.615 %; the mass percentage of oxygen is 100(15.9994/73.857) or 21.663 %; and the mass percentage of hydrogen is (100)(2.00000)(1.00794)/73.857) or 2.7294 %.

What is the percentage mass of oxygen in cocaine?
Cocaine is C17H21NO4 and has a molar mass of 303.353 g/mole. Mass of oxygen in cocaine is 4x16 = 64. So, % oxygen by mass is 64/303.353 (x100) = 21% (to 2 sig. figs)
