Calculate the force of gravity between Earth (mass=6.0*10^24 kg) and the moon (mass=7.4*10^22 kg). The average Earth-moon distance is 3.8*10^8 m.

The answer I got was 2.05*10^20 Newtons, but it seems like it could possibly be too big. Am I wrong?

I have 6.673E-11*7.4E22*6.0E24/(3.8E8)^{2}= your number.
