I have an unknown volume of a gas held at a temperature of -153 celsius in a container with a pressure of 60.0 atm. If by increasing the temperature to -48 degrees celsius and decreasing the pressure to 30.0 atm causes the volume of the gas to become 29.0 L, how many liters of gas did I start with?

Keep answer in correct sig figs, space then unit.
