Solution

To convert water hardness from parts per million (ppm) to grains per gallon (gpg), you need to know that 1 grain per gallon is approximately equal to 17.1 parts per million.

Here are the steps to convert 154 ppm to gpg:

  1. Take the given value in ppm, which is 154 ppm.
  2. Divide this value by the conversion factor, which is 17.1 ppm/gpg.

So, 154 ppm ÷ 17.1 ppm/gpg = approximately 9 gpg.

Therefore, a water hardness of 154 ppm is approximately equal to 9 gpg.
