What is the mass percent of oxygen in the compound Mn3(PO4)2?
a. Calculate the molar mass of the entire compound.
b. Calculate the mass of the oxygen that is in the compound (count up how many oxygens are in the compound, and multiply it by the molar mass of oxygen).
c. Divide the mass of the oxygen in the compound by the total molar mass, and then multiply that by 100%.
The Mass Percentage of an Element:
The mass percentage of an element in the compound is a percentage that represents how much the mass of the element makes up of the mass of the compound. That means that the mass of the element contributes to the mass of the compound. So the higher the mass percentage of the element, the more the mass of the element contributes to the mass of the compound.
