How many miles will a car go on a 12.0 gallon tank that gets 40.0 mpg? (mpg 40.0 = 1 gallon)

The car will travel 480 miles when the tank has 12 gallons.

Explanation:

We are given that the car is moving with a speed of 40 miles/gallon.

We need to find the distance traveled by the car when the tank is filled with 12 gallons, we use unitary method.

In 1 gallon, the car is travelling 40 miles.

So, in 12 gallons, the car will travel miles

Hence, the car will travel 480 miles when the tank has 12 gallons.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

it's all four options.
