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      

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell
