Semimolar solution contains how many moles of solute in 1L of solution?

Options

A. 1
B. 0.1
C. 0.5
D. 0.001

Explanation

To determine how many moles of solute are present in a semimolar solution in 1 liter of solution, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Molarity**: Molarity (M) is defined as the number of moles of solute divided by the volume of solution in liters. The formula is:
\[ M = \frac{\text{Number of moles of solute}}{\text{Volume of solution in liters}} \]

2. **Identify Semimolar Solution**: A semimolar solution is a solution that has a molarity of 0.5 M. The term "semi" indicates that it is half of a standard molar solution (1 M).

3. **Calculate Moles in 1 Liter**: Since a semimolar solution has a molarity of 0.5 M, this means that in 1 liter of this solution, there are:
\[ \text{Number of moles of solute} = 0.5 \, \text{moles} \]

4. **Conclusion**: Therefore, a semimolar solution contains 0.5 moles of solute in 1 liter of solution.

### Final Answer:
A semimolar solution contains **0.5 moles** of solute in 1 liter of solution.
