The molarity of 0.006 mole of NaCl in 100ml solution is

Options

A. `0.6`
B. `0.06`
C. `0.066`
D. None of these

Explanation

To find the molarity of a solution, we can use the formula:

\[ \text{Molarity (M)} = \frac{\text{Number of moles of solute}}{\text{Volume of solution in liters}} \]

### Step-by-Step Solution:

1. **Identify the number of moles of solute**:
- Given: Number of moles of NaCl = 0.006 moles.

2. **Convert the volume of the solution from milliliters to liters**:
- Given: Volume of solution = 100 mL.
- To convert mL to L, use the conversion factor: \(1 \text{ L} = 1000 \text{ mL}\).
- Therefore, \(100 \text{ mL} = \frac{100}{1000} \text{ L} = 0.1 \text{ L}\).

3. **Substitute the values into the molarity formula**:
\[ \text{Molarity (M)} = \frac{0.006 \text{ moles}}{0.1 \text{ L}} \]

4. **Calculate the molarity**:
\[ \text{Molarity (M)} = 0.006 \div 0.1 = 0.06 \text{ M} \]

### Final Answer:
The molarity of 0.006 mole of NaCl in 100 mL solution is **0.06 M**.
