How many moles are present in 4.7 liters of Argon gas at STP?

The answer for the following problems is mentioned below.

Explanation:

Mole:

The mass of a substance containing the same number of fundamental units as there are atoms in exactly 12.000 g of .

Given:

volume (v) = 4.7 litres

Volume of argon at STP conditions = 22.4 litres

To find:

volume of argon at STP conditions

We know;

n =

where;

n represents the no of moles

v represents the volume of the argon

V represents the volume of argon at STP

volume of the argon at STP conditions is 22.4 litres

So;

n =

n = 0.20 moles

Therefore the number of moles present in Argon is 0.20 moles.
