A vessel containing Ne(g) and Ar(g) has a total pressure of 9.78. If the partial pressure of the Neon (PNe) is 3.78 and the partial pressure of the Argon (PAr) is 6, then the mole-fraction of Ne(g) is and the mole-fraction of Ar(g) is .

Answer : The mole fraction of and is, 0.387 and 0.613 respectively.

Explanation :

According to the Dalton's Law, the partial pressure exerted by component 'i' in a gas mixture is equal to the product of the mole fraction of the component and the total pressure.

Formula used :

where,

= partial pressure of gas

= mole fraction of gas

= total pressure of gas

Now we have to determine the partial pressure of and

Given:

and,

Given:

Therefore, the mole fraction of and is, 0.387 and 0.613 respectively.
