calculate the molarity of a solution made by dissolving 0.750 grams of Na2SO4 in enough water to form exactly 850 mL of solution.

• Chemistry -

that is right. but if it is 0.850 grams of Na2s04 it is completely diffrent.

• Chemistry -

I don't know what Aron is talking about.
mols Na2SO = grams/molar mass = ?
M = mols/L = ?mols/0.850L = zxx
