CONVERTING MOLE TO MASS
Calculate the number of grams of SO2 that could be produced from 3.25 moles of oxygen (moles 02 →
moles SO2 → g SO2). AW of O = 16 9. S = 32.065 g
4FeS + 702 → 2Fe2O3 + 4SO2 (balanced equation)
Using mole-mass analysis on balanced chemical reaction we can find amount of SO3 produced.
4FeS + 702 → 2Fe2O3 + 4SO2(balanced equation)
7mole of O2 4mole of SO2
3.25mole of O2 ?
mole of O2
Molar mass of SO2=[32.065+2(16)]g/mol
N.o. of grams of SO2=1.857mol×64.065g/mol
Mass of SO2 Formed =118.97g
Therefore :-118.97g of SO2 can be produced.
