In that situation, if the mass of solute is 1 g and the amount of solute is 0.01 mol, what is its molar mass?
Answer and explanation
Correct answer: 100 g mol⁻¹
Molar mass is calculated by dividing the mass of a substance by its amount in moles: M = m/n. Here the mass is 1 g and the amount is 0.01 mol. Thus, M = 1 g ÷ 0.01 mol = 100 g mol⁻¹. The answer must have units of grams per mole because grams are divided by moles. Therefore, option C is correct. This is a basic mole-concept calculation.
