Calculate the mass of phosphoric acid required to obtain 53.4g pyropho

1.	Calculate the mass of phosphoric acid required to obtain 53.4g pyrophorshric acid
Answer» Molecular MASS of pyrophosphoric acid = 177.98 G/mol mass of pyrophosphoric acid produced = 53.4 g molar mass of phosphoric acid = 98 g/mol number of moles in 53.4 g of phosphoric acid = 53.4/ 177.98 = 0.3 From the above eqn. 1 mol of pyrophosphoric acid is produced by 2 mol of phosphoric acid mass of 2 moles of phosphoric acid = 2 x 98 = 196 g mass of phosphoric acid required for FORMATION of 1 mol of pyrophosphoric acid = 196 g mass of phosphoric acid required for formation of 0.3 mol of pyrophosphoric acid = 0.3 x 196 = 58.8 g
