Solution: A. A balloon is floating around outside your window. The temperature outside is 13 ° C, and the air pressure is 0.700 atm. Your neighbor, who released the balloon, tells you that he filled it with 4.5

Problem

A. A balloon is floating around outside your window. The temperature outside is 13 ° C, and the air pressure is 0.700 atm. Your neighbor, who released the balloon, tells you that he filled it with 4.50 moles of gas. What is the volume of gas inside this balloon? Express your answer to three significant figures and include the appropriate units.

B. A 18.0 L gas cylinder is filled with 8.00 moles of gas. The tank is stored at 49 ° C. What is the pressure in the tank? Express your answer to three significant figures and include the appropriate units.

C. A 240. L kiln is used for vitrifying ceramics. It is currently operating at 1335 °C, and the pressure is 1.075 atm. How many moles of air molecules are within the confines of the kiln? Express your answer to three significant figures and include the appropriate units.
