Solution: A sample of gas (24.2 g) initially at 3.00 atm was compressed from 8.00 L to 2.00 L at constant temperature. After the compression, the gas pressure was ________ atm.a) 4.00b) 8.00c) 12.0d) 16.0e)
Problem
Solution
A sample of gas (24.2 g) initially at 3.00 atm was compressed from 8.00 L to 2.00 L at a constant temperature. We’re being asked to determine the pressure of the gas after compression.
Recall that the ideal gas law is:
The pressure and volume of a gas are related to the number of moles, gas constant and temperature. The value nRT is constant.
