A car uses 12.5 L of gasoline to travel a distance of 275 km. Convert this into units of miles per gallon (mi/gal).

The mileage of the car is 51.75 mil/gal.

Explanation:

Distance covered by the car = 275 km =

1 Mile = 1.609 kilometer

Volume of gasoline used by the car = 12.5 L =

1 gallon = 3.785 Liter

Mileage of the car :

=

The mileage of the car is 51.75 mil/gal.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
