Clark mass is 81 kg. Find his weight on earth and the moon and hiss mass on the moon?

MASS= 81kg= 81000g gravity on earth= 10m/s2 Weight=mass*gravity =>81000*10= 810,000N ~~~~~~~~~~~~~~~~~~~ gravity on moon=1.5g =>81000*1.5= 121,500N. ___________________ MASS ON MOON; if w=mg then; =>121,500N= 1.5g 121,500/1.5=1.5/1.5 81000g .'. In Gram=81kg
