How is the mass percent of an element in a compound calculated?
AElement mass over molar mass, times 100
BMoles of element over litres of solution
CAtoms of element divided by molecules
DCompound mass over element mass, times 100
Answer & Solution
Correct answer: A. Element mass over molar mass, times 100
Mass percent is the mass of the element in one mole of compound divided by the molar mass, multiplied by 100.
