11g of salt is present in 55g of solution. Calculate the mass percentage of the solution.

Options

A. 30%
B. 10%
C. 20%
D. 40%

Explanation

To calculate the mass percentage of salt in the solution, follow these steps:

### Step 1: Identify the mass of the solute and the mass of the solution.
- **Mass of solute (salt)** = 11 g
- **Mass of solution** = 55 g

### Step 2: Use the formula for mass percentage.
The formula for mass percentage is given by:

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

### Step 3: Substitute the values into the formula.
Substituting the values we have:

\[ \text{Mass Percentage} = \left( \frac{11 \, \text{g}}{55 \, \text{g}} \right) \times 100 \]

### Step 4: Simplify the fraction.
Now, simplify the fraction:

\[ \frac{11}{55} = \frac{1}{5} \]

### Step 5: Calculate the mass percentage.
Now, multiply by 100:

\[ \text{Mass Percentage} = \left( \frac{1}{5} \right) \times 100 = 20\% \]

### Conclusion:
The mass percentage of the solution is **20%**.
