Answer : The number of moles present in ammonia is, 70.459 moles.
Solution : Given,
Mass of ammonia = [tex]1.2\times 10^3g[/tex]
Molar mass of ammonia = 17.031 g/mole
Formula used :
[tex]\text{Moles of }NH_3=\frac{\text{ given mass of }NH_3}{\text{ molar mass of }NH_3}[/tex]
[tex]\text{Moles of }NH_3=\frac{1.2\times 10^3g}{17.031g/mole}=70.459moles[/tex]
Therefore, the number of moles present in ammonia is, 70.459 moles.
