A flexible container at an initial volume of 8.15 L contains 6.51 mol of gas. More gas is then added to the container until it reaches a final volume of 15.9 L. Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container.

A balloon taken out of a freezer is going to expand. The amount of a gas inside the balloon remains the same, and the atmospheric pressure inside and outside the freezer is the same. Explain this phenomenon using gas laws.

A gas sample is held at constant pressure. The gas occupies 3.62 L of volume when the temperature is 21.6°C. Determine the temperature at which the volume of the gas is 3.13 L.

A container with helium gas, neon gas, and argon gas has a total pressure of 17.4 atm. The partial pressure of helium is 1.8, the partial pressure of neon gas is 3.5. What is the partial pressure of argon, in units of atm, in the container?

A sample of gas at 35.8 psi is heated from 25.0 °C to 100.0 °C. Assuming the volume is constant, what is the pressure (in atm) of the gas at 100.0 °C?

A flexible container at an initial volume of 8.15 L contains 8.51 mol of gas. More gas is then added to the container until it reaches a final volume of 18.7 L. Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container. number of moles of gas: mol

If 1.52 g Ar are added to 3.41 atm He in a 2.00 L cylinder at 27.0 °C, what is the total pressure of the resulting gaseous mixture? Ptotal = atm

A flexible container at an initial volume of 7.14 L contains 9.51 mol of gas. More gas is then added to the container until it reaches a final volume of 12.1 L. Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container. number of moles of gas: mol

A flexible container at an initial volume of 5.12 L contains 7.51 mol of gas. More gas is then added to the container until it reaches a final volume of 13.5 L. Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container. number of moles of gas: mol

4. A glass container was initially charged with 2.00 moles of a gas sample at 3.75 atm and 21.7 °C. Some of the gas was released as the temperature was increased to 28.1 °C, so the final pressure in the container was reduced to 0.998 atm. Assume the volume stayed the same. How many moles of the gas sample are present at the end?
