Asked by Cici
How many moles of gas must be forced into a 5.2 L tire to give it a gauge pressure of 30.6 psi at 26 ∘C? The gauge pressure is relative to atmospheric pressure. Assume that atmospheric pressure is 14.9 psi so that the total pressure in the tire is 45.5 psi .

I believe you should have written the 45.5 as 45.5 psia if it is 30.6 psi.
Use PV = nRT
For P convert 45.5 to atm.
Remember to convert T to kelvin.
Solve for n. Post your work if you get stuck.
