The mass of (NH4)3PO4 is 111.75grams.
HOW TO CALCULATE THE MASS:
- The mass of a substance can be calculated by multiplying the number of moles by its molecular mass. That is;
mass (g) = moles (mol) × molar mass (g/mol)
- Molar mass of (NH4)3PO4 is calculated as follows:
{14 + 1(4)}3 + 31 + 16(4)
= (14+4)3 + 31 + 64
= 54 + 31 + 64
= 149g/mol
mass in grams = 149 × 0.75
mass in grams = 111.75g
Therefore, the mass of (NH4)3PO4 is 111.75grams.
