Four samples of gas each exert 675 mm Hg in separate 3.5 L containers. What pressure will they exert if they are all placed in a single 3.5 L container?

a. 169 mm Hg

b. 675 mm Hg

c. 2.36 x 103

d. 2.70 x 103

The pressure that will be exerted if four sample of gas are placed in a single 3.5 container is calculated as below

if each gas occupies 675 mmhg

what about 4 gases in the sample

by cross multiplication

= 675 mm hg x 4/1 = 2.7 x10^3mmhg (answer D)
