2: How many milliliters of an aqueous solution of 0.219 M chromium(III) sulfate is needed to obtain 3.70 grams of the salt?
____ml
Molarity =
w is mass of solute ( chromium sulfate) = 3.70 g
M is molar mass of chromium sulfate = 392 g/mol
V is volume of solution (mL)
Given ,
Molarity = 0.219 M
Hence,
0.219 =
Or, V =
Or, V = 43.1 mL.
Hence, 43.1 mL of an aqueous solution is needed.
