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.

5 answers

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
0.50
