Question

The mass of solute is expressed as 116 ppm. What is its mass percent

Answer 1

Answer:-

1ppm=11000000

1ppm=0.0001%

So to convert from ppm to percent, divide the ppm by 10000

Hence mass percentage = 11610000=0.0116%

Answer 2

Given,

mass of solute = 116 ppm

To Find,

Mass percentage

Solution,

This is a way of expressing the concentration of soluble substances. Just as a percentage means hundreds, so fractions per million or ppm mean a million. It usually refers to the fullness of something in the water or on the ground. One ppm equals 1 milligram per liter of water (mg / l) or milligram per kilogram of soil (mg/kg).

The mass percentage of 1 ppm is

1 ppm = (1*100)/1000000

          = 0.0001‰

Now,

116 ppm = 116*0.0001

              = 0.0116 ‰

Hence, the mass percentage of solute is 0.0116‰
