Molarity calculations

Question

A 0.200L cup of tea contains 3.765 g sucrose, which has the molecular weight of 342.3 g/mol. what is the molar concentration of sucrose in the tea?

Answer 1

moles = (weight in grams) / (molecular weight) = (3.765 g) / (342.30 g/mol) = 0.011 mols

molarity = (moles of solute) / (volume of solution in liters)

molarity = (0.011 mols ) / (0.200 L) = 0.055 mols/L
