An arctic weather balloon is filled with 24.2 L of helium gas inside a prep shed. The temperature inside the shed is 12. °C. The balloon is then taken outside, where the temperature is -29. °C. Calculate the new volume of the balloon. You may assume the pressure on the balloon stays constant at exactly 1 atm. Be sure your answer has the correct number of significant digits.

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.

40 mL of oxygen gas at a temperature of 42 degrees Celsius is heated to 183 degrees Celsius. What is the new volume? Use 273 for the conversion of Celsius to Kelvin. Do not type units in your answer.

A marine biologist is preparing a deep-sea submersible for a dive. The sub stores breathing air under high pressure in a spherical air tank that measures 68.0 cm wide. The biologist estimates she will need 8400. L of air for the dive. Calculate the pressure to which this volume of air must be compressed in order to fit into the air tank. Write your answer in atmospheres. Be sure your answer has the correct number of significant digits. 0 atm x10 x Ś
