Question

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

Answer 1

3 moles of the diatomic green
--> p1=0.63 atm = 3×2 atoms
p2 is 6 moles of blue
p3 is 5 moles of orange
P-total (Pt) = p1 + p2 + p3
Pt = 0.63 + 0.63 + (0.63)(5)/6
Pt = 1.26 + 0.525 = 1.79 atm

Answer 2

Answer:

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):

$Xi = \frac{molecules of the gas}{total molecules of the mixture} \\\\Xi = \frac{3}{14} \\\\Xi = 0.214$

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.
