Question

Calculate the gram molecular mass of nh4cl &na3po4

Answer 1

HII MATE HERE IS YOUR ANSWER
MOLECULAR WEIGHT OF NH4Cl is (14)+ 4(1)+ 1(35.5)= 14+4+35.5=18+35.5=53.5 g/ mol
MOLECULAR WEIGHT OF Na3PO4
= 3(23) + 1(31) + 4(16)= 69 +31+64= 164 g/ mol

Answer 2

The molecular mass of ammonium chloride is 53.5 g/mol and that of sodium phosphate is 164 g/mol

Explanation:

Molecular mass is defined as the sum of masses of individual atoms in a compound. It is expressed in g/mol.

It is also the mass of 1 mole of a compound.

We are given:

Two chemical formulas of compounds which is: $NH_4Cl\text{ and }Na_3PO_4$

• Molecular mass of $NH_4Cl$ :

Molar mass of nitrogen = 14 g/mol

Molar mass of hydrogen = 1 g/mol

Molar mass of chlorine = 35.5 g/mol

Molecular mass of $NH_4Cl=[(1\times 14)+(4\times 1)+(1\times 35.5)=53.5g/mol$

• Molecular mass of $NH_4Cl$ :

Molar mass of sodium = 23 g/mol

Molar mass of phosphorus = 31 g/mol

Molar mass of oxygen = 16 g/mol

Molecular mass of $Na_3PO_4=[(3\times 23)+(1\times 31)+(4\times 16)=164g/mol$
