Question

A sample of oxygen gas has a volume of 205 cm cubed when its temperature is 22.0 degrees C and its pressure is 30.8 kPa. What volume will the gas occupy at STP?

Answer 1

V2 = 57.67cm3

Step-by-step explanation:

From the question

P1= 30.8, V1=205cm3, T1= 22+273=295K, P2=101.325kPa, T2= 273K, V2= ?

Applying

P1V1/T1= P2V2/T2

Substitute and simplify

(30.8*205)/295 = (101.325*V2)/273

V2= 57.67cm3
