A 5.00 % m/m glucose solution has d = 1.02 g/mL. What is the mass of glucose in 375 mL of the solution? Enter only the numeric value for your answer (no units).

5% m/m (w/w) means 5 g glucose in 100 g solution. Use the density to calculate the volume of 100 g soln. Call that v. Then

5g x (375 mL/v mL = g/375.
