moles of gas. A sample of krypton gas that occupies a volume of 28.2 L at a temperature of 0 °C and a pressure of 1 atm contains

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 1.23 mol sample of xenon gas is collected at a pressure of 521 mmHg and a temperature of 16.0°C. The volume of the sample is L.

A sample of hydrogen gas at a pressure of 1.18 atm and a temperature of 267 °C, occupies a volume of 612 mL. If the gas is heated at constant pressure until its volume is 737 mL, the temperature of the gas sample will be   ____°C.   (Explain well with proper step  by step Answer. ).

0.596 mol sample of xenon gas at a temperature of 28.0 °C is found to occupy a volume of 22.6 liters. The pressure of this gas sample is ____ mm Hg.

A sample of helium gas collected at a pressure of 1.25 atm and a temperature of 302 K is found to occupy a volume of 828 milliliters. How many moles of He gas are in the sample?

A sample of carbon dioxide gas at a pressure of 0.589 atm and a temperature of 23.9 °C, occupies a volume of 19.5 liters. If the gas is allowed to expand at constant temperature to a volume of 25.4 liters, the pressure of the gas sample will be atm.

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?

A certain mass of nitrogen gas occupies a volume of 8.20 L at a pressure of 1.78 atm. At what pressure will the volume of this sample be 10.58 L? Assume constant temperature and ideal behavior.
