Determining sulfur ppm from 1ml/gal of 1 molar H2SO4

[Peat_Phreak]

Can anyone verify or debunk my result?

1M H2SO4 weight is 98.078 g / l or 0.09878 g / ml

Then I used hydrobuddy to get 7.156ppm of S from 1ml of 1M sulfuric acid per gallon of water.

I typically use about 5ml / gal. So the acid is giving me about 35ppm of S while I pH down?

I think it's right or close to it. Not 100% sure.

It seems like a good way to supply some extra sulfur without adding any other element.
