How many mols do you need? That's mols = M x L = ?
The mols = grams/molar mass. You know mols and molar mass, solve for grams.
If you are asked to make exactly 1.0 Liter of 0.80 M ZnCl2 solution, how many grams of zinc chloride would you need to be massed out? How do I go about solving this problem?
