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.

The molecular polarity and bond type of PCl3 is polar.
An accepted and universally true explanation of observed facts is a law.
Answer: A. 
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed = 4.56 J
m = mass of substance = 123 g
c = specific heat capacity = ?
Change in temperature ,
Putting in the values, we get:
The specific heat of a 123 g substance that requires 4.56 J of heat in order to increase its temperature by 12.32 °C is
