A355-ml soft drink sample contains 0.133 mol of sucrose (table sugar). What is the molar concentration of sucrose in the

beverage?

0.375mol/L

Explanation:

Well you were given the mole of solute (n) = 0.133 and the volume of solvent (V) = 355mL

Note that the molar Conc. also called Molarity = (n) the mole of solute / (V) the volume of solvent

But keep in mind that the volume should always be in liter (L). Therefore, convert mL to L by dividing 1000:

V = 355mL/1000 = 0.355L

In the end, we apply the formula:

M = n/V

M = 0.133/0.355 = 0.3746mol/L ≈ 0.375mol/L
