What is the volume occupied by 51.0 g of ammonia gas (nh3) at stp?

Answer :  The volume of ammonia gas at STP is, 67.2 liters

Explanation : Given,

Mass of ammonia = 51.0 g

Molar mass of ammonia = 17 g/mole

As we know that,

At STP, 1 mole of gas contains 22.4 L volume of gas.

First we have to calculate the moles of ammonia gas.

Now we have to calculate the volume of ammonia gas at STP.

As, 1 mole of ammonia gas contains 22.4 L volume of ammonia gas

So, 3 moles of ammonia gas contains volume of ammonia gas

Therefore, the volume of ammonia gas at STP is, 67.2 liters
