Answer:
n = 13.23 mol
Step-by-step explanation:
Volume = 72 L
Pressure = 344.4 KPa (344.4/101 = 3.4 atm)
Temperature = 225 K
Moles of gas = ?
Solution:
PV = nRT
n = PV/RT
n = 3.4 atm . 72 L / 0.0821 atm. L /mol. K . 225 K
n = 244.8 mol /18.5
n = 13.23 mol

Answer:
c) The balloon might pop due to increase in volume of gas by the heat.
Step-by-step explanation:
It is known that every thing expend on heating. when balloon is inflated to its capacity in summer it will pop because gas inside it get warmer because of heat and gas molecules move faster because of high kinetic energy. Thus gas expand and put force on balloon which then get explode.
