The number of moles of the solute present in 600 ml of 0.5M solution is:

Explanation

To find the number of moles of solute present in 600 ml of a 0.5 M solution, we can follow these steps:

### Step 1: Convert the volume from milliliters to liters.
Given:
- Volume = 600 ml

To convert milliliters to liters, we use the conversion factor:
\[ 1 \text{ L} = 1000 \text{ ml} \]
Thus,
\[ \text{Volume in liters} = \frac{600 \text{ ml}}{1000} = 0.6 \text{ L} \]

### Step 2: Use the molarity formula to find the number of moles.
The formula for molarity (M) is given by:
\[ M = \frac{\text{Number of moles}}{\text{Volume of solution in liters}} \]
We can rearrange this formula to find the number of moles:
\[ \text{Number of moles} = M \times \text{Volume in liters} \]

### Step 3: Substitute the values into the formula.
Given:
- Molarity (M) = 0.5 M
- Volume = 0.6 L

Now substituting these values:
\[ \text{Number of moles} = 0.5 \times 0.6 \]

### Step 4: Calculate the number of moles.
\[ \text{Number of moles} = 0.3 \text{ moles} \]

### Final Answer:
The number of moles of solute present in 600 ml of a 0.5 M solution is **0.3 moles**.
