An electric car has a mass of 2,000 kg. the engine is producing a force of 3,500 N to move the vehicle forward, but it must overcome air friction equal to 500 N What is the acceleration of the electric car m/s2?

Explanation:

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

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
