Phosphoric acid is very important compound used to make fertilizers.PPhosphoric acid can be prepared in two ways: Reaction 1: P4 + 5O2 = P4O10. Reaction 2: P4O10 + 6H29 = 4H3PO4. Supposing we allow 272 g of phosphorus to react with excess oxygen which forms tetra phosphorus decoxide in 96.8% yield. In the second step reaction, a 96.8% yield of H3PO4 is obtained. Work out the mass of H3PO4 obtained?
1 answer
Produced mass of H3PO4 =62/4×31×0.85×0.9×4×98=149.94g
