consider a balloon that will expand without restriction until it pops. If the balloon can hold a maximum of 5.0 L gas before it pops, and you're filling the balloon at a mass flow rate of 3.0g/s of hydrogen gas, determine how long you can fill the balloon before it pops if the gas and the surrounding atmosphere is at 26 c take the outside pressure to be 0.97 atm
