Homework Equations
pV = nRT
The Attempt at a Solution
I assumed that volume and temperature would stay constant. I assumed the volume wouldn't change because the volume of the tire doesn't change. This implies that
n1/p1 = n2/p2
n1p2 / p1 = n2
I found n1 by using the ideal gas law
pV/RT = n1 = 0.0592 moles of gas
Then I used the first equation to find n2 = 0.0431 moles.
Subtracting n1 - n2 I found that 0.0161 moles of gas escaped from the tire.
Converting the amount of moles lost to grams I get
0.0161 x 28 g N2/ 1 mol N2 = 0.451 g of N2 gas
The correct answer should be 1.8 g
