Help me solve part A and B
Transcribed Image Text:Dalton's law states that the total pressure, Ptotal of a
mixture of gases in a container equals the sum of the
pressures of each individual gas:
Ptotal
= P₁+P+ P3+...
The partial pressure of the first component, P₁, is equal
to the mole fraction of this component, X₁, times the
total pressure of the mixture:
P₁ = X₁ X Ptotal
The mole fraction, X, represents the concentration of
the component in the gas mixture, so
X₁
-
moles of component 1

Part A
Three gases (8.00 g of methane, CH, 18.0 g of ethane, C₂H6, and an unknown amount of propane, C3Hg) were added to the same
10.0-L container. At 23.0 °C, the total pressure in the container is 4.20 atm. Calculate the partial pressure of each gas in the container.
Express the pressure values numerically in atmospheres, separated by commas. Enter the partial pressure of methane first,
then ethane, then propane.
