Homework Help: Chemistry

Posted by Timoefy on Friday, May 24, 2013 at 3:47pm.

Estimate the number of moles of gas (and mass of gas assuming that it is all N2) inside your family car (or a friends if you don't have one). If the amount of gas was compressed at constant temperature to fit inside a coke can what would the pressure inside the coke can be?

Did i solve this correctly,

28.317 l x 115ft^3 = 3256 l at a standard temperature (0 C, 40 F)
3256 l x 1mole N2/22.44 l = 145.4 moles N2
Number of moles = 145.4 moles N2

145.4 moles N2/22.4 l = 6.49
28/6.49=4.3
Im kind of stuck right here, what do i need to do next?
