Question

Calculate the molecular weight of the following substance
(d)Ammonium Nitrate$\left[{\mathrm{NH}}_4{\mathrm{NO}}_3\right]$

Answer 1

• One molecule of Ammonium Nitrate$\left[{\mathrm{NH}}_4{\mathrm{NO}}_3\right]$ contains two nitrogen atoms(Atomic weight=14 AMU), four Hydrogen atoms(Atomic weight=1), and three Oxygen atoms(atomic weight=16).
• The molecular weight of Ammonium Nitrate$\left[{\mathrm{NH}}_4{\mathrm{NO}}_3\right]$ will be $\left(2\times 14\right)+\left(4\times 1\right)+\left(3\times 16\right)=28+4+48=80\mathrm{amu}$
