Question

. How many moles of ammonia gas, NH3, are required to fill a volume of 50 liters at STP?

Answer 1

in STP every 22.4 litters is 1 mol

Answer 2

Answer : The number of moles of ammonia gas is, 2.232 moles

Explanation : Given,

Volume of ammonia gas = 50 L

As we know that at STP,

1 mole of gas contains 22.4 L volume of gas.

As, 22.4 L volume of ammonia gas present in 1 mole of ammonia gas

So, 50 L volume of ammonia gas present in
`(50)/(22.4)=2.232` mole of ammonia gas

Therefore, the number of moles of ammonia gas is, 2.232 moles
