D=m÷v
so density would be 57.9 ÷ 3 = 19.3 g/cm³
The computation would be:moles = mass/ Molar Mass, but we are looking for the mass, so rearranging, will give us: mass = moles x MM
Q = moles x Hf
Q = (mass/MM) x Hf
mass = (Q x MM) / Hf
= (1.50-kJ x 18.0-g/mol) / 6.01-kJ/mol
=4.49 g H20 is the answer
Just do energy spent divided by time to get your answer :). With this we can say a human might be able to!
