Question

A2.09-L sample of gas at (574.6°C. 0.447 atm) is cooled to 310.6°C. Assuming constant pressure, calculate the final volume of the gas. Answer: L Note: you may enter your answer in E notation Example: 1.5x10 in E notation is 1.5E-6. Example: 10 , which is the same as 1x10., in E notation is 1E36.)

Answer 1

ANSWER:

Given,

Volume, V1 = 2.09 L

Temperature, T1 = 574.6 oC = 847.75 K

Pressure, P = 0.447 atm

Temperature, T2 = 310.6 o​​​​C = 583.75 K

We know that,

PV = nRT

Here P, n & R is constant. So,

For two condition :

V 2.09L 847.75K 538.75K)

So, V2 = 1.33 L or 13.3E-1 L

Hence, final volume of gas is 13.3E-1 Litres.
