At 528 torr and 21.0 oC, a gas has a volume of 224 mL. The gas conditions change to a volume of 778 mL and its temperature is adjusted until the pressure is 445 torr.  What is the new temperature in oC?

A sample of a gas at room temperature occupies a volume of 25.0 L at a pressure of 352 torr . If the pressure changes to 1760 torr , with no change in the temperature or moles of gas, what is the new volume, V2?

A weather balloon is inflated with helium to a volume of 635.0 L at sea level, where the temperature is 30.0°C and the barometric pressure is 760.0 torr. The balloon rises to an altitude of 4500.0 feet where the pressure is 645.0 torr and the temperature is 6.0°C. What is the change in volume (in liters) of the balloon in going from sea level to 4500.0 feet?

A sample of gas at 195 °C has a volume of 36.2 L. If it is cooled to 108 °C, at constant pressure, what is its new volume?

A 20.0 L container at 303 K holds a mixture of two gases with a total pressure of 5.00 atm. If there are 1.14 mol of Gas A in the mixture, how many moles of Gas B are present?

A gas occupies 547 mL at 596.0 Torr and 26.9 °C. When the pressure is changed to 326.5 Torr, what temperature is needed to maintain the same volume?

A tank contains helium gas at 490 mmHg, nitrogen gas at 0.75 atm, and neon at 520 torr. What is the total pressure in atm?

A sample of gas has a mass of 0.565  g g . Its volume is 115  mL mL at a temperature of 86  ∘C ∘C and a pressure of 755  Torr Torr . Find the molar mass of the gas.   Use the molar volume of a gas at STP to determine the volume (in LL) occupied by 19.8  g g of neon at STP.

A sample of helium gas occupies a volume of 6.79 L at 60.0°C and 391 torr. If the volume of the gas sample is decreased to 4.61 L, while its temperature is increased to 131.0°C, the resulting gas pressure will be torr.

A tank contains helium gas at 191 mm Hg, nitrogen gas at 0.261 atm, and neon at 522 torr. What is the total pressure in mm Hg?
