A gas storage cylinder in an ordinary chemical laboratory measures 7.2 cm wide and 29. cm high. This is the label on it. Contents: N, gas Pressure: 18.6 atm If the cylinder is opened and the gas allowed to escape into a large empty plastic bag, what will be the final volume of nitrogen gas, including what's collected in the plastic bag and what's left over in the cylinder? Write your answer in liters. Be sure your answer has the correct number of significant digits.

An arctic weather balloon is filled with 21.7 L of helium gas inside a prep shed. The temperature inside the shed is 9. °C. The balloon is then taken outside, where the temperature is -32. °C. Calculate the new volume of the balloon. You may assume the pressure on the balloon stays constant at exactly 1 atm. Round your answer to 3 significant digits. L ☐ X 3

Gaseous ethane CH3CH3 will react with gaseous oxygen O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. Suppose 19. g of ethane is mixed with 52.1 g of oxygen. Calculate the minimum mass of ethane that could be left over by the chemical reaction. Be sure your answer has the correct number of significant digits.
