Calculate the molecular mass of H3po4?

To calculate the molecular mass of H3PO4 (phosphoric acid), we need to find the sum of the atomic masses of all the atoms in the molecule.

The atomic masses are as follows:
H (hydrogen) = 1.00784 g/mol
P (phosphorus) = 30.97376 g/mol
O (oxygen) = 15.999 g/mol

Now, let's calculate the molecular mass:

H3PO4 = (3 * H) + P + (4 * O)
= (3 * 1.00784) + 30.97376 + (4 * 15.999)
= 3.02352 + 30.97376 + 63.996
= 97.99328 g/mol

Therefore, the molecular mass of H3PO4 is approximately 97.99328 g/mol.
