A person heats a balloon. If the balloon initially has a volume of 0.40 L and a temperature of
22 °C, what will the volume of the balloon be after she heats it to a temperature of 249 °C if
pressure stays constant. What gas law is this?

Estimate the molar mass of the gas that effuses at 1.6 times the effusion rate of carbon dioxide.
