Calculate the mass of H2O produced by metabolism of 2.6kg of fat, assuming the fat consists entirely of tristearin (C57H110O6), a typical animal fat, and assuming that during metabolism, tristearin reacts with O2 to form only CO2 and H2O.

Answer 1

This is not physics.

write the chemical reaction, and balance it.

Then look at how many moles of H20 one gets from one mole of tristearin.

fugure the moles of fat from 2.6kg
then use the mole ratio to figure the moles of water.
