Question 10
The amount of helium in a balloon is difficult to determine because it is difficult to weigh. However, it is possible by knowing some quantities. A helium balloon was found to have a volume of 6.8 L at 30 °C and 1 atm. Determine the mass of helium inside the balloon. Use R=0.0821 L-atm/mol-K, M=4 g/mol for He
