Answer to Question #303393 in General Chemistry for justin

Question

A sample of gas occupies a volume of 300 ml at a pressure of 0.5 atm and a temperature of 22 0 C.

Calculate the new pressure if the volume is decreased to 220 ml at a constant temperature.

Answer 1

• P¹V¹/T¹=P²V²/T² here

1. P²= 1.25- atm
2. V²=?
3. T²=345K
4. P¹=0.75-atm
5. V¹=120
6. T¹=295K

• So V²= (0.75 x120/295)x(345/1.25)
• Volume of the gas V²= 84.20- ml
