Chemistry Question: Pressurized carbon dioxide inflators can be used to inflate a bicycle tire…?

Pressurized carbon dioxide inflators can be used to inflate a bicycle tire in the event of a flat. These inflators use metal cartridges that contain 16.0 g of carbon dioxide.

moles CO2 = 16.0 g / 44.009 g/mol=0.364

p = nRT/V = 0.364 x 0.08206 x 294 / 3.08 = 2.85 atm

1 atm = 14.7 psi

pressure = 14.7 x 2.85 =41.9 psi

p = 41.9 – 14.7 = 27.2 psi
