ppm (parts per million) is usually used to describe solution concentrations.

You should look up these terms:

empirical formula

mass fraction


1g of C4H6CaO4 has approximately 253mg. of elemental calcium.

EDIT: So the answer to your original question is: False. If you had to express the mass fraction of calcium in CaAc in ppm, it would be ~253,000ppm.

Thank you kindly to all who replied!!

I see the error of my ways now!
I asked the question wrong!

Here is what I should have said:
If Calcium acetate is about 25.3% elemental calcium or 253 mg/g.
If I add 1 gram Calcium acetate AKA 253 mg of elemental calcium to 1 liter of water I should have 253 PPM of calcium as we speak of it in fertilizers is that correct?

When we speak of calcium in fertilizes are we speaking of elemental calcium?


And I am trying to completely comprehend empirical formula and mass fraction as we speak.

How in the world do you brainy people find the time to smoke with all this silly studying going on!!!! GeeZe!
:smoke out:
Thanks again

Yes, we speak of elemental Calcium. And yes, your above calculation is correct.

What if you're working with the more common monohydrate instead of the anhydrous salt?

Nice! Yes i went in search of one with no N and i ended up making up with calcium oxide and some epsom salts..separately
In veg yes CalciumNitrate with MagnesiumNitrate but sometimes i change the NCa for the calcium oxide to dont overload in N...
I was wondering out of curiosity if was possible put in the same bottle diluted or in powder some calcium and some magnesium without creating reactions...:pimp3:
