110g of salt is present in 550g of solution. Calculate the mass percentage of the solution.

Options

A. 10%
B. 20%
C. 30%
D. None

Explanation

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

### Step 1: Identify the mass of the solute and the mass of the solution.
- The mass of the solute (salt) = 110 g
- The mass of the solution = 550 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.
Now, we can substitute the known values into the formula:

\[ \text{Mass Percentage} = \left( \frac{110 \, \text{g}}{550 \, \text{g}} \right) \times 100 \]

### Step 4: Simplify the fraction.
We can simplify the fraction:

\[ \frac{110}{550} = \frac{1}{5} \]

### Step 5: Calculate the mass percentage.
Now, we can calculate the mass percentage:

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

### Final Answer:
The mass percentage of salt in the solution is **20%**.
