Find the concentration of solution in terms of weight percent if 30g of common salt is dissolved in 65g of water..

Explanation

To find the concentration of a solution in terms of weight percent, follow these steps:

### Step 1: Identify the masses of solute and solvent
- Mass of solute (common salt) = 30 g
- Mass of solvent (water) = 65 g

### Step 2: Calculate the total mass of the solution
- Total mass of solution = Mass of solute + Mass of solvent
- Total mass of solution = 30 g + 65 g = 95 g

### Step 3: Use the formula for weight percent concentration
- The formula for weight percent concentration is:
\[ \text{Weight percent} = \left( \frac{\text{Mass of solute}}{\text{Mass of solution}} \right) \times 100 \]

### Step 4: Substitute the values into the formula
- Mass of solute = 30 g
- Mass of solution = 95 g
- Weight percent = \(\left( \frac{30 \text{ g}}{95 \text{ g}} \right) \times 100\)

### Step 5: Calculate the weight percent
- Weight percent = \(\left( \frac{30}{95} \right) \times 100 \approx 31.58\%\)

### Final Answer
The concentration of the solution in terms of weight percent is approximately **31.58%**.
