Question

What is the molar mass of MgNH4PO4x6H2O?

a) 245.30 g/mol
b) 245.50 g/mol
c) 246.20 g/mol
d) 246.40 g/mol

Answer 1

The molar mass of MgNH4PO4x6H2O is 245.50 g/mol.

Step-by-step explanation:

The molar mass of MgNH4PO4·6H2O can be determined by adding up the molar masses of each element in the compound.

Molar mass of Mg: 24.305 g/mol

Molar mass of N: 14.007 g/mol

Molar mass of H: 1.008 g/mol

Molar mass of P: 30.974 g/mol

Molar mass of O: 16.00 g/mol

Adding up these masses gives:

24.305 + 4(1.008) + 30.974 + 4(16.00) + 6(1.008) = 245.50 g/mol

Therefore, the molar mass of MgNH4PO4·6H2O is 245.50 g/mol.
