A tire has a volume of 3 ft3 and a gage pressure of 32 psi at 75 o F. If the ambient pressure is sea-level standard, how much does the air in the tire weigh

Explanation:

Relation between density and pressure is as follows.

         P =

            = 6724.8

Value of R = 1716

           T =

Now, we will calculate the density as follows.

                        = 0.007325

Therefore, density of the air is 0.007325 .

Now, we will calculate the weight of the air as follows.

           W =

               =

               = 0.215 lbf

Therefore, weight of the tire in air is 0.215 lbf.

i think the answer is d. but im not sure!

it is the second option.
