Step-by-step explanation:

It is required the atomic masses of all elements that take part in this molecule:

MgNH4PO4.6H2O

-----

From the periodic table:

Mg) 24.3 u

N) 14.0 u

H) 1.00 u

P) 31.0 u

O) 16.0 u

-----

After that, the molecular weight is calculated as follows:

The molecular weight = 1 x 24.3 (Mg) + 1 x 14.0 (N) + 4 x 1.00 (H) + 1 x 31.0 (P) + 4 x 16.0 (O) + 6 x 2 x 1.00 (H) + 6 x 16.0 (O) = 245.3 g/mol approx.

Answer: 245.3 g/mol
