Question

The molar mass of sucrose, or table sugar, is 342 grams. Calculate how many grams of sucrose are required to make 3.0 liters of 0.50M sucrose solution.
Two definitions to know:
(1)
Molarity = #mols/liter of solution.

(2)
# mols = grams/molar mass.

From #1, you know molarity and liters, calculate mols. From #2, plug in mols and molar mass to calculate grams.
513 g
