You have a freshly prepared 0.1 M sucrose (molecular mass 342) solution, which means ________.

Question

Quizplus · Accepted Answer

0.1 M sucrose means that there are 0.1 moles of sucrose per liter of solution. The molecular mass of sucrose is 342 g/mol. Therefore, 0.1 moles of sucrose have a mass of 0.1 x 342 = 34.2 g. Avogadro's number is 6.02 × 10^23, which is the number of entities (atoms, molecules, ions, etc.) in one mole of a substance. Therefore, 0.1 moles of sucrose contain 6.02 × 10^22 (i.e. one-tenth of Avogadro's number) sucrose molecules. Thus, both options D are correct statements about the solution.
