Suppose 17 grams of sucrose is dissolved into 183 grams of water. What is the concentration of sucrose in ppm?

85 x 10³ ppm

Explanation:

Data Given:

mass of sucrose = 17 g

mass of water = 183 g

Concentration in ppm = ?

Solution:

Formula Used

Concentration (ppm) = Solute / Solution x 10⁶ ... (1)

**Note : 1 ppm = 1 mg / L

First we have to know about mass of solution

So

Mass of solution = mass of solute + mass of solvent ... (2)

Put values in equation 2

Mass of solution = 17 g sucrose + 183 g water

Mass of solution = 200 g

Now Put Values in equation 1

Concentration (ppm) = Solute / Solution x 10⁶

Concentration (ppm) = 17 g / 200g x 10⁶

Concentration (ppm) = 0.085 x 10⁶

Concentration (ppm) = 85 x 10³

Concentration of sucrose = 85 x 10³ ppm
