Atmospheric pressure..........

Question

A sample of oxygen gas occupies 300.0 mL at 27ºC and atmospheric pressure. What volume does it occupy at 150ºC and the same pressure?

A. 150 mL

B. 4.7 L

C. 423 mL

D. 1.67 L

E. 213 mL

Answer 1

P1V1T2 = P2V2T1

at constant pressure becomes:

V1T2 = V2T1

(300) (423K) = (V2)(300K)

V2 = 423 ml

your answer is: C. 423 mL
