For the first part, just remember the definition. molarity = # mols/Liter of solution.
AND mols = grams/molar mass.
Using equation 1, you know molarity and you know liters, calculate mols.
Using equation 2, you know mols and molar mass, calculate grams.
How do I solve this?
How many grams of solid NaOH are required to prepare 200 mL of a 0.05 M solution? What will be the concentration expressed in % W/V?
