You have a freshly prepared 0.1 M solution of glucose in water. Each liter of this solution contains how many glucose molecules?
(1) 6.02 * 10 ^ 23
(3) 6.02 * 10 ^ 24
(2) 3.01 * 10 ^ 23
(4) 6.02 * 10 ^ 22
Let’s break down the problem:
Given:
- Concentration of glucose solution: 0.1 M
- Molarity (M) is defined as moles of solute per liter of solution.
So, a 0.1 M solution means that there are 0.1 moles of glucose in 1 liter of the solution.
Step-by-Step Calculation:
- 1 mole of any substance contains Avogadro’s number of molecules, which is approximately 6.02 × 10²³ molecules.
Therefore, the number of glucose molecules in 1 liter of a 0.1 M glucose solution is:
Final Answer:
The correct answer is (4) 6.02 × 10²² molecules.
