Question

The volume of gas at 320mmHg and 22⁰c is 220cm³. What volume would the gas occupy at s.t.p ?

Answer 1

Answer: 85.73 cm^3

Step-by-step explanation:

Combined Gas law (temperature must be in Kelvin)

V2= P1V1 T2/(T1 x P2)

P1 = 320 mmHg

V1= 220 cm^3

T1= 295.15 K

T2= 273.15 K

P2 = 760 mmHg

320 x 220 X 273.15/(295.15 X 760) = 85.72697201 cm^3
