At the end of 2012, global population was about 7.0 billion people. What mass of glucose in kg would be needed to provide 1200 c
al/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 thermo-chemical equation: C₆H₁₂O₆(s)+6O₂(g)⟶6CO₂(g)+6H₂O(l); ΔH₀ = −2803kJ

We have 30% (w/w) HCl this means :
100 g solution contains 30 g HCl
?? g solution contains 7.5 g HCl
By cross multiplication:
Mass of solution =
= 25 g solution
100 g solution contains 30 g HCl
?? g solution contains 7.5 g HCl
By cross multiplication:
Mass of solution =
