Answer : The number of moles present in ammonia is, 70.459 moles.
Solution : Given,
Mass of ammonia = ![1.2\times 10^3g](https://tex.z-dn.net/?f=1.2%5Ctimes%2010%5E3g)
Molar mass of ammonia = 17.031 g/mole
Formula used :
![\text{Moles of }NH_3=\frac{\text{ given mass of }NH_3}{\text{ molar mass of }NH_3}](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20%7DNH_3%3D%5Cfrac%7B%5Ctext%7B%20given%20mass%20of%20%7DNH_3%7D%7B%5Ctext%7B%20molar%20mass%20of%20%7DNH_3%7D)
![\text{Moles of }NH_3=\frac{1.2\times 10^3g}{17.031g/mole}=70.459moles](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20%7DNH_3%3D%5Cfrac%7B1.2%5Ctimes%2010%5E3g%7D%7B17.031g%2Fmole%7D%3D70.459moles)
Therefore, the number of moles present in ammonia is, 70.459 moles.
