Step 1 of 3

Solution 12Q

The percent composition is the sum of all the percentages of each element in the compound. The molecular formula mass is 100% or the total of the compound. So the first thing is to find the molar mass from the chemical formula.Find the molar mass, Find the mass of each element Divide the mass of the element by the molar mass x 100 = %
