Solve for the unknown. Show your solution. 1.) A balloon that contains 1,500 mL of air at 2.00 atm is taken underwater to a depth at which the pressure is 4.00 atm. Calculate the new volume of the balloon. Assume the temperature remains constant. 2.) A gas sample with a fixed quantity of 28.0 °C has a volume of 12.5 L. Calculate the volume the gas will occupy if the temperature increases to 115 °C while the pressure is held constant. 3.) A gas initially at STP is changed to 248 K. Calculate the final pressure of the gas. 4.) A particular gas has a volume of 5.0L at 75.0 °C and 600.0 mmHg. Calculate the temperature if the volume decreased to 3500.0 mL and the pressure is increased to 780. mmHg.

1.) A balloon that contains 1,500 mL of air
at 2.00 atm is taken underwater to a depth at
which the pressure is 4.00 atm. Calculate the new
volume of the balloon. Assume the temperature
remains constant.
2.) A gas sample with a fixed quantity of 28.0
°C has a volume of 12.5 L. Calculate the volume
the gas will occupy if the temperature increases
to 115 °C while the pressure is held constant.
3.) A gas initially at STP is changed to 248 K.
Calculate the final pressure of the gas.
4.) A particular gas has a volume of 5.0L at 75.0 °C
and 600.0 mmHg. Calculate the temperature
if the volume decreased to 3500.0 mL and the
pressure is increased to 780. mmHg.
5.) If 0.00100 moles of hydrogen gas at 155
°C exert a pressure of 323 mmHg. What is the
volume?
