Question

1.A 1-Lflask is filled with 1.30gof argon at 25 ?C. A sample of ethane vaporis added to the same flask until the total pressure is1.25atm.

PartA

What is the partial pressure of argon,PAr, in the flask?Express your answer to three significant figures and includethe appropriate units.

PartB

What is the partial pressure ofethane, Pethane, in the flask?

Express your answer to threesignificant figures and include the appropriate units.

2.Would thevolume be different if the sample were 12.8

g of helium (under identical conditions)?(PartA .What is thevolume occupied by 12.8

gof argon gas at a pressure of 1.00atmand a temperature of 349K?V=9.15L)V=9.15

Would the volume be different if the samplewere 12.8 of helium (under identical conditions)?

	The volume would be the lower forhelium gas.
	The volume would be the greater forhelium gas.
	The volume would be the same forhelium gas.
