Answer to Question #167968 in General Chemistry for KORIE

Question

Please with STEPS

A sample of carbon dioxide gas at a pressure of  672 torr and a temperature of 34.1 C, occupies a volume of 712 mL. If the gas is compressed at constant temperature until its pressure is 862 torr, the volume of the gas sample will be...........  mL.

Answer 1

pV=nRT

R = 62.36 L⋅Torr⋅K⁻¹⋅mol⁻¹

672 x 0.712 = n x 62.36 x (34.1+273)

n = 0.025 mol

862 x V = 0.025 x 62.36 x (34.1+273)

V = (0.025 x 62.36 x (34.1+273)) / 862 = 0.555 L
