Homework Statement
hey guys I've got a problem, could you tell us where i went wrong
Lithopone is a brilliant white pigment used in water-based interior paints. It is a mixture of barium sulfate and zinc sulfide produced by the reaction
BaS(aq) + ZnSO4(aq) ZnS(s) + BaSO4(s)
What mass of lithopone in grams (to 3 significant figures) is produced in the reaction of 227 mL of 0.257 M ZnSO4 and 325 mL of 0.280 M BaS?
MY WORKED SOLUTION"
Mole of BaS=0.280*0.325=0.091mole
mole of ZnSO4=0.0257*0.277=0.0712moles <therefore this is limiting
i don't know what i should take the molarmass of to work out the mass?
ANSWER IS 1.93 grams
anyhelp would be GREATFULLY appreciated.
