A 1.75-L container filled with CO2 gas at 25 °C and 225 kPa pressure springs a leak. When the container is re-sealed, the pressure is 165 kPa kPa and the temperature is 12 °C. How many moles of gas were lost?
J. UT UULU VUUPALUWW A sample of nitrogen gas is collected in a 100 mL container at a pressure of 688 mmHg and a temperature of 565 °C. How many grams of nitrogen gas are present in this sample?
A glass container was initially charged with 1.70 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. How many moles of the gas sample are present at the end?
