Calculate the mass of the salt obtained by reacting 56 grams of a 20% KOH solution with a H2SO4 solution, if the mass fraction of the product yield is 95%
Decision:
56 * 0.2 = 11.2 (g.) – m (KOH)
n (KOH) = 11.2 / 56 = 0.2 (mol)
n (K2SO4) = 0.1 mol
m (K2SO4) = 0.1 * 174 = 17.4 (g.)
17.4 * 0.95 = 16.53 (g.)
