If the partial pressure of the diatomic gas is 0.630 atm what is the total pressure?

2.944 ATM

Explanation:

There are 14 molecules of gas mixture: 5 molecules of orange gas, 6 of blue gas and 3 of green gas. The green gas is the diatomic gas because it's formed by two atoms. The blue and the orange are monoatomic gases.

By the Dalton's Law, the partial pressure of a gas in a mixture of gas, may be calculeted knowing its molar fraction (Xi):

Dalton's Law: Pi = Xi x Pt

0.630 = 0.214xPt

Pt = 2.944 ATM

Obs: The number of significant algorism such be the same of all parcels of the equation, including the result.
