A sample of glucose (C6H12O6) of mass 8.44 g is dissolved in
2.11 kg water. What is the
freezing point of this solution? The freezing point depression
constant, Kf, for water is
1.86°C/mol.
The reaction of glucose, C6H12O6, to carbon dioxide and water is
a common reaction in the body. C6H12O6 (s) + _6__ O2 (g) → __6__
CO2 (g) + __6__ H2O (g)
If you eat 15.0 g of glucose from some candy you eat, how many
grams of carbon dioxide will you produce?
If the density of water at body temperature (37 ⁰C) is 0.9933
g/mL, how many mL of water is produced from this reaction?
The osmotic pressure of blood is 7.65 atm at 37 °C. What mass of
glucose (C6H12O6, molar mass = 180.2 g/mol) is needed to prepare
2.50 L of solution for intravenous injection? The osmotic pressure
of the glucose solution must equal the osmotic pressure of blood.

3. Which of the following...
In photosynthesis, green plants convert carbon dioxide and water
into glucose (C6H12O6) according to the following equation:
6CO2(g)+6H2O(l)→ C6H12O6(aq)+6O2(g). Estimate ΔH for the reaction
using bond dissociation energies from Table 7.1. Give your answer
in kcal/mol and kJ/mol. C6H12O6 has five C−C bonds, seven C−H
bonds, seven C−O bonds, and five O−H bonds. Express your answers as
integers separated by a comma.
Consider the reaction where glucose is oxidized to ethanol and
