Question

A sample of oxygen, O 2 , occupies 32. 2 mL at 30 °C and 452 torr. What volume will it occupy at –70 °C and the same pressure?

Answer 1

21.58 mL

Step-by-step explanation:

this is Charles' law

V1/T1 = V2/T2

Temperature must be in Kelvin

V2= V1 X T2 / T1

32.2 x203.15 / 303.15

dont need pressure since its the same.
