Calculate the molar Concentrations for the given problem. A 355-mL soft drink sample contains 0.133 mol of sucrose (table sugar). What is the molar concentration of sucrose in the beverage?

Solution:

Since the molar amount of solute and the volume of the solution are both given, the molarity calculated using the definition of molarity. Per this definition, the solution volume converted from mL to L:

M = mol solute / L solution

= 0.133 mol / [355mL x (1L/1000mL)]

= 0.375 M

Sucrose
