Concept explainers
(a)
Interpretation:
Glucose and sucrose undergo combustion with oxygen and produce carbon dioxide and water.
Number of moles of oxygen required per mole of each sugar for the reaction completion has to be calculated.
(b)
Interpretation:
Number of grams of oxygen required per mole of each sugar for the reaction completion has to be calculated.
Concept introduction:
Molar mass of a substance is the mass in grams of one mole of a substance.
(c)
Interpretation:
From the given combustion reaction, the formation of more water per gram sugar has to be identified. Number of grams of water produced per gram of each sugar for the reaction has to be calculated.
Concept Introduction:
Refer subpart (b)
