What does the ideal gas law allow a scientist to calculate that the other gas laws do not?

The ideal gas law allows a scientist to calculate the number of moles that the other gas laws do not. The ideal gas law is given as

P V = n RT

rearranging the equation by dividing both side by "RT", we get

PV/(RT) = nRT/(RT)

n = PV/(RT)

inserting the values of pressure, volume and temperature, we get number of moles.

the higher the current the higher the mag field around it the higher the influence on the compass

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
