Question

Calculate the molar mass of ${\mathrm{Na}}_2\mathrm{O}$

Answer 1

• Molecular mass is defined as the total sum of the masses of the atoms or elements present in the molecule is termed molecular mass.

Molecular mass of ${\mathrm{Na}}_2\mathrm{O}$ = $2\times \mathrm{atomic}\mathrm{mass}\mathrm{of}\mathrm{Na}+\mathrm{Atomic}\mathrm{mass}\mathrm{of}\mathrm{O}$

=$2\times 23\mathrm{u}+16\mathrm{u}$

=$62u$

Conclusion- Molar mass of ${\mathrm{Na}}_2\mathrm{O}$ is 62u
