Question

A sample of helium gas has a volume of 2.0 L at a pressure of 4.0 atm. What is the volume of gas at each of the following pressures? A sample of helium gas has a volume of 2.0 L at a pressure of 4.0 atm. What is the volume of gas at each of the following pressures? Question Be sure to answer all parts. A sample of helium gas has a volume of 2.0 L at a pressure of 4.0 atm. What is the volume of gas at each of the following pressures? The temperature and the number of gas particles do not change. a. 6.5 atm b. 17.3 atm

Explanation / Answer

when temperaure and number of gas particles do not change.

then P1 * V1 = P2 * V2

a) 6.5 atm.

4.0 * 2.0 = 6.5 * V2

V2 = 1.23 L

so volume of gas is 1.23 L

b) 17.3 atm

4.0 * 2.0 = 17.3 * V2

V2 = 0.46 atm

so volume of gas is 0.46 L
