EEJ MAIN Chemistry QUESTION #7529

Question 1

What mass of sucrose (C$_{12}$H$_{22}$O$_{11}$, molar mass = 342 g mol$^{-1}$) is required to prepare 2 L of a 0.1 M aqueous solution?

Correct Answer Explanation

Moles needed $= M \times V = 0.1\ \text{mol/L} \times 2\ \text{L} = 0.2\ \text{mol}$

Mass $= 0.2 \times 342 = \mathbf{68.4\ \text{g}}$
