Question

What mass of sucrose, C12H22O11, is needed to make 500mL of a 0.20M solution?

Help please...

Thanks.

Answer 1

mass= molmasssucrose*molarity*volumeinliters.

Answer 2

You want 0.2 M.
M = mols/L or mols = L x M = 0.5 x 0.2 = ?? mols sucrose.
mols = grams sucrose/molar mass sucrose
Solve for grams.
