What are the molecular weights of H3PO4?
For example, a molecule of the compound H3PO4 contains three hydrogen atoms, one phosphorus atom, and four oxygen atoms. The molar mass is obtained by adding up the average atomic masses of these atoms: Molar mass H3PO4 = 3(1.008 g) + 1(30.97 g) + 4(16.00 g) = 97.99 g.
How do you find the mass of H3PO4?
– 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.
