Question

calculate the relative molecular mass of- (nh4)3po4​

Answer 1

Answer:

Molar mass=3(14.0)+12(1.0)+31.0+4(16.0)=149g/mil.

step3:Divide the mass of nitrogen by the molar mass of(NH4)3PO4 and multiply by 100% to get percent mass.

step4:find the total mass of all the hydrogen atoms in one mole of compound.

Answer 2

Given: The given compound is $(NH_4)_3PO_4$.

To find: We have to find the relative molecular mass.

Solution:

The compound is $(NH_4)_3PO_4$.

The atomic mass of N is 14 and the atomic mass of H is 1.

The atomic mass of Oxygen is 16 and the atomic mass of P is 31.

This compound has three N atoms, 12 H atoms, one P atom and four oxygen atoms.

Thus, the relative molar mass will be-

$3 \times 14 + 12 \times 1 + 31 + 4 \times 16 \\ 42 + 12 + 31 + 64 \\ = 149$

The relative molar mass is 149 gram.
