An average healthy man needs about 10000 kJ of enrgy per day.How much carbohydrates (in mass) he will have to consume assuming that all this energy needs are met only by carbohydrates in the form of glucose? The enthalpy of combustion of glucose is `2816 kJ "mol"^(-1)`.

Explanation

To find out how much carbohydrates (in mass) a healthy man needs to consume to meet his daily energy requirement of 10,000 kJ, we will follow these steps:

### Step 1: Understand the Energy Requirement
The average healthy man requires 10,000 kJ of energy per day.

### Step 2: Know the Enthalpy of Combustion of Glucose
The enthalpy of combustion of glucose (C₆H₁₂O₆) is given as 2816 kJ/mol. This means that burning one mole of glucose releases 2816 kJ of energy.
