# Problem: At the end of 2012, global population was about 7.0 billion people. What mass of glucose in kg would be needed to provide 1600 cal/ person / day of nourishment to the global population for one year? Assume that glucose is metabolized entirely to CO2 (g) and H2O (l) according to the following thermochemical equation:C6H12O6 (s) + 6O2 (g) 6 (g) + 6H2O(l)Ho= - 2803

We’re being asked to convert 1600 cal/person/day to kJ/glucose/year

We will do conversions to solve the problem. We will do the following steps:

Step 1: Convert person/day to year

Step 2: Convert cal to kJ

Step 3: Convert kJ to kg

Step 1: Convert person/day to year

Here is the flow to convert person/day to yearcal/person/day (person) → cal/day (day/year) → cal/year ###### Problem Details
