E connect CHEMISTRY Question oints 3 atempts e Check my work Be sure to answer all parts. A man ate 0.552 pund of cheese (an energy intake of 3.50 x 10kJ). Suppose that none of the energy was stored in his body. What mass (in grams) of water would he need to perspire in order to maintain his original temperature? (t takes 44.0 lJ to vaporize 1 mole of water.) Enter your answer in scientific notation x10

Explanation / Answer

The energy equivalent cheese =3.5x 103 kJ

To evaporate 1 mole of water = 18g , we need to use 44.0kJ of energy.

thus to maintain the original temperature , he needs to use all the energy taken form cheese.

Thus

44 .0kJ heat is used to evaporate 18g of water

3.5x103 kJ heat can evaporate = 3.5x 1000 x 18 /44

= 1431.8 g of water

Thus he needs to perspire 1431.8g of water to maintain his body temperature
