A solution contains 30g of common salt dissolved in 470 g of water. The concentration of solution is

Explanation

To find the concentration of the solution, we can follow these steps:

### Step 1: Identify the mass of solute and solvent
- The mass of the solute (common salt) is given as 30 grams.
- The mass of the solvent (water) is given as 470 grams.

### Step 2: Calculate the mass of the solution
- The mass of the solution is the sum of the mass of the solute and the mass of the solvent.
- Mass of solution = Mass of solute + Mass of solvent
- Mass of solution = 30 g (solute) + 470 g (solvent) = 500 g

### Step 3: Calculate the concentration of the solution
- The concentration of the solution can be calculated using the formula:

\[ \text{Concentration} = \left( \frac{\text{Mass of solute}}{\text{Mass of solution}} \right) \times 100 \]

- Plugging in the values:

\[ \text{Concentration} = \left( \frac{30 \, \text{g}}{500 \, \text{g}} \right) \times 100 \]

- Calculating the concentration:

\[ \text{Concentration} = \left( 0.06 \right) \times 100 = 6\% \]

### Final Answer
- The concentration of the solution is **6%**.
