Question

calculate volume in meter cube occupied by 170 g of NH3 of STP​

Answer 1

Answer:

Given: Mass of ammonia at STP = 170g

Molecular mass of NH3 = 17g

First, we will calculate the number of moles by applying the formula given in the attachment

Number of moles = 10

Thus, number of moles of CaCO3 is 10

Now 1 mole of any gas occupies 22.4 litres of volume.

∴ 1 mole of NH3 = 22.4 litre

10 moles of NH3 = 22.4 × 10 = 224 litres

Thus, the volume occupied by 170g of NH3 is 224 litres.
