Question

how we found molecular weight of phosphoric acid​

Answer 1

Answer:

The molecular weights of hydrogen, phosphorus and oxygen are 1, 31 and 16 respectively. - Therefore the molecular weight of the phosphoric acid is as follows. 3 (H) + (P) + 4(O) = 3 (1) + 31 + 4(16) = 3 + 31 + 64 = 98. - So, the molecular weight or molar mass of the phosphoric acid is 98.
