32. Solving a chemistry problem

1. Hydrogen fluoride is obtained from fluorite containing 92% CaF2. In this case, 96% sulfuric acid (ρ = 1.96 g/ml) is used, which is taken in a 40% excess. The reaction yield is 95%. Calculate the volume of HF (N.O.) obtained from 100 kg of fluorite and the volume of acid consumed.
