A 700.0 mL gas sample at STP is compressed to a volume of 200.0 mL, and the temperature is increased to 30.0 degrees Celsius. What is the new pressure of gas at kPa?

Answer:

We will use the formula PV = nRT

We are told that initial conditions are STP

That means Temperature = 273.15 K

Pressure 100kPa
