Question

You have a sample of a gas that occupies a volume of 17mL at -111 degrees Celsius. What volume does the sample occupy at 88 degrees Celsius? Show all work PLEASE HELP ASAP

Answer 1

Ans: Volume at 88 C = 7.6 ml

Given:

Initial volume of gas V1 = 17 ml

Initial temperature T1 = -111 C

Final temperature T2 = 88 C

To determine:

Final volume V2

Step-by-step explanation:

Based on ideal gas law:

PV = nRT

at constant P and n

V/T = constant

or V1/T1 = V2/T2

V2 = (V1/T1)*T2

= 17 ml (-111+273)K/(88+273)K = 17 ml(162 K/361 K) = 7.6 ml
