If 15% (m/m) NaOH solution has a total mass of 375 g, how much NaOH was used to make this sample?
the mass by mass percentage of solution is 15 %
total mass of solution = 375 g
Mass of NaOH used in this process = "\\frac{15 \\times 375}{100}=56.25 g"
Mass of NaOH used to make this solution = 56.25 g
