A solution contains 6 mg isopropanol dissolved in 2 kg H2O. The isopropanol concentration is?

the concentration of isopropanol is 3 ppm.

Explanation:

The isopropanol concentration is

As we know that

Concentration = mass isopropanol ÷mass of water

= 6 mg ÷ 2 kg

= 3 mg/Kg

Now convert 3 mg/Kg to ppm.

As we know that

1 mg/Kg = 1 ppm

So,  

 3 mg/Kg = 3 ppm

Hence, the concentration of isopropanol is 3 ppm.
