The answer for the following problems is mentioned below.
Therefore the number of moles present in Argon is 0.20 moles.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 =![\frac{v}{V}](/tpl/images/0612/7494/10f1d.png)
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 =![\frac{4.7}{22.4}](/tpl/images/0612/7494/e1c55.png)
n = 0.20 moles
Therefore the number of moles present in Argon is 0.20 moles.
