The mineral vanadinite has the formula pb5(vo4)3cl. what mass percent of chlorine does it contain?
1 answer:
The molar mass of vanadinite is 1416.27 g/mol. Looking at
the molecular formula we can see that there is 1 mole of Cl for every mole of
vanadinite. Therefore:
mass percent = [(1 mole Cl * 35.45 g/mol) / (1 mole
Pb5(VO4)3Cl * 1416.27 g/mol)] * 100%
<span>mass percent = 2.50% </span>
