Question

Human body requires 2370 kcal of energy daily the heat of combustion of glucose is -790 Kilo calories per mole .The amount of glucose required for daily consumption is

Answer 1

Answer:The amount of glucose required for daily consumption is 240 g.

Explanation:

Total energy required by human body= 2370 kilo calorie

Energy required for combustion of 1 mole of glucose = -790 kilo calorie

780 kilo-calorie of heat is produce by =  1 mole of glucose \

Then 2370 kilo calorie will be produced by = $\frac{2370 k-cal}{790 k-cal}$that is 3 moles of glucose

Mass of glucose =Number of moles × Molar mass of glucose  

= 3 mole × 180 gram/mol = 240 grams

The amount of glucose required for daily consumption is 240 g.
