Need help with 1-3 challenge questions. Thank you

Consider a balloon that will expand without any restriction until it pops. If the balloon
can hold a maximum of 6.6 L of gas before it pops, and you're filling the balloon at a mass flow
rate of 0.184 g/s of hydrogen gas, determine how long (in seconds) you can fill the balloon before
it pops if the gas and the surrounding atmosphere is 35 °C and the outside of pressure is 1.08
atm.
Challenge Questions:
1) When sodium metal is placed in water, it reacts to form sodium hydroxide and hydrogen
gas. If 35.4 grams of sodium is placed in 48.9 mL of water, what volume of hydrogen gas will be
produced, assuming the temperature is 28 °C and the pressure is 670 mmHg (the approximate
atmospheric pressure in El Paso).
2)
A 35 m long gas pipeline made from Schedule 40 PVC pipe that is 3.25 cm in diameter
is used to transport butane to a residential house's stove. The pip can withstand 9789.23 kPa at
25 °C. Determine the maximum mass of gas the pipe can hold.
3)
A paintball gun's air-tank can handle 3700,0 psi (25511 kPa) until the seal breaks. If the
air- tank is filled with compressed air to a pressure of 3200.0 psi (22063) kPa at a temperature of
26.333 °C. determine the following:
a.
The pressure inside the air- tank if the paintball gun is brought outside on a hot summer
day and the temperature of the gas inside the tank reaches 38.9 °C
b.
Does the seal break under the condition of part a?
