whoops, made a typo. It's sulfur, not sulfure.
Sodium sulfate is Na2SO4.
1 mol Na2SO4 contains 1 mol S.
1 mol Na2SO4 has a mass of 142.04 g.
Convert 2.01 g Na2SO4 to mols and since 1 mol Na2SO4 contains 1 mol S, that will be the mols of S, also.
2.01 x (1 mol Na2SO4/142.04 g Na2SO4) x (1 mol S/1 mol Na2SO4) = ?? mols S in 2.01 g Na2SO4. Note how the units you don't want to keep cancel and the unit you want (mols S in this case) don't cancel. Check my work.
awesome! thanks for the help!
