Question

A sample of argon gas at a pressure of 0.972 atm and a temperature of 23.5 °C, occupies a volume of 679 mL. If the gas is allowed to expand at constant temperature until its pressure is 0.588 atm, the volume of the gas sample will be ____ mL.

Answer 1

Initial conditions P = 0.972 atm V 679 m2 Final Conditions P₂ = 0.588 atn. = ? Relation between P and v at constant temperature PV = P₂ = (0.972 atm ) ( 679 mi) 0.588 atm - => 1122.43mL 1.12 x 103 mL = = ₂ ņ three sig. I rounded to figurea 11. 12X10 ML T122.43mL
