1000 gram aqueous solution of `CaCO_(3)` contains 10 gram of carbonate. Concentration of solution is:

Options

A. 10 p pm
B. 100 ppm
C. 1000 ppm
D. 10,000 ppm

Explanation

To find the concentration of the solution in parts per million (ppm), we can follow these steps:

### Step 1: Understand the Definition of ppm
Parts per million (ppm) is a way to express very dilute concentrations of substances. It is defined as the mass of solute (in grams) per million grams of solution.

### Step 2: Identify the Given Values
From the problem, we know:
- Mass of the aqueous solution = 1000 grams
- Mass of carbonate (CaCO₃) = 10 grams

### Step 3: Calculate the Concentration in ppm
Using the formula for ppm:
\[ \text{ppm} = \left( \frac{\text{mass of solute (g)}}{\text{mass of solution (g)}} \right) \times 10^6 \]

Substituting the values we have:
\[ \text{ppm} = \left( \frac{10 \text{ g}}{1000 \text{ g}} \right) \times 10^6 \]

### Step 4: Simplify the Calculation
Calculating the fraction:
\[ \frac{10}{1000} = 0.01 \]

Now, multiply by \(10^6\):
\[ 0.01 \times 10^6 = 10,000 \]

### Step 5: State the Final Answer
The concentration of the solution is:
\[ \text{Concentration} = 10,000 \text{ ppm} \]
