The number of moles of the solute present in 500 ml of 0.06M solution is:

Options

A. 0.01
B. 0.02
C. 0.03
D. 0.04

Explanation

To find the number of moles of solute present in a 500 ml solution with a molarity of 0.06 M, we can follow these steps:

### Step 1: Convert the volume from milliliters to liters
We know that 1 liter is equal to 1000 milliliters. Therefore, to convert 500 ml to liters, we use the conversion:
\[ \text{Volume in liters} = \frac{500 \text{ ml}}{1000} = 0.5 \text{ L} \]

### Step 2: Use the molarity formula
Molarity (M) is defined as the number of moles of solute divided by the volume of the solution in liters:
\[ \text{Molarity} = \frac{\text{Number of moles}}{\text{Volume in liters}} \]
Given that the molarity is 0.06 M and the volume is 0.5 L, we can rearrange the formula to find the number of moles:
\[ \text{Number of moles} = \text{Molarity} \times \text{Volume in liters} \]

### Step 3: Substitute the values into the formula
Now we can substitute the values we have:
\[ \text{Number of moles} = 0.06 \, \text{M} \times 0.5 \, \text{L} \]

### Step 4: Calculate the number of moles
Now we perform the multiplication:
\[ \text{Number of moles} = 0.06 \times 0.5 = 0.03 \, \text{moles} \]

### Conclusion
The number of moles of solute present in 500 ml of a 0.06 M solution is **0.03 moles**.
