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.
