It's 32°F (0°C) outside under normal atmospheric conditions (1 atm) at a stunt performer's birthday party. There is a huge blue balloon filled with flammable hydrogen (H₂, molar mass = 2.02 g/mol) gas that she plans to safely ignite, causing a massive explosion. Inside the balloon is 243 g of H₂(g). What is the volume of the balloon, in liters? Round to the nearest whole number.
