On a perfect fall day, you are hovering at low altitude in a hot-air balloon, accelerated neither upward nor downward. The total weight of the balloon, including its load and the hot air in it, is 24000 N.

Find the weight of the displaced air.

!!I got this: it is 2.4×10^4 N

I cannot get the volume please help!!

Find the volume of the displaced air.

For the volume of displaced air, divide the mass (W/g = 2446 kg) by the density of air, which is about 1.3*10^-3 kg/m^3, depending upon P and T.
