Worksheet 4 . Topic 1
Set C: Gas law calculations Objective: To test your ability to set-up and solve gas law problems
For each question below, write down the factors given, set-up the problem using the combined gas
law equation, and solve for the unknown factor.
16. At constant pressure, a 3.5 L sample of oxygen gas is at 280 K. If the temperature is increased to 560 K,
calculate the new volume of the gas.
Determine factors from question. Write down the gas law equation, set-up and solve
P1 = P2 =
