20%
In order to reduce the percentage of acid from 80% to 50%, you would need to add another 36 kg of diluent (e.g. water).
54 kg
Approx 60kg (at 4oC)
Work=force*displacement=(588.6 N)(1.2 m)=706.32 which is about 700 J for sig figs displacement=1.2 m force (needs to equal gravity so it can counteract gravity)=m g=(60kg)(9.81 m/s^2)=588.6 N
well you need to convert into pounds from kg or inches into meters. then you could go: as W=mgh, m=60kg, g=9.81ms^-2, h=(height of each step) break an equation into each step, add all the steps together..... then we could say: 9.81x60kg(6in+ 12in+ 18in+ 24in etc etc)......twelve times to gain the total number of steps. adding all together will gain the total work done.

Assuming a pupil is a human being, the average adult human body contains about 16% carbon by weight. So in a 60kg pupil, there would be approximately 9.6kg of carbon.
