Explanation: Solved in the attached picture.
The molar concentration of the sucrose is 13M.
What is molar concentration?
The best way to describe a solution's solute concentration is in terms of molar concentration. The total number of moles of dissolved solute per liter of solution is referred to as molarity.
What is sucrose?
The monosaccharide sugars glucose and fructose are joined to form sucrose, a disaccharide, or two-part molecule. Invertases are digestive enzymes that help honeybees break down plant nectars into honey, which is primarily a mixture of sucrose, glucose, and fructose.
Therefore, the molar concentration of the sucrose is 13M.
