I have found a cheap source of Mag Citrate and Zn Citrate in NSW

Australia (email privately for details) but need to figure out how

much I am getting per gram as I am buying per kg.

High school chem is locked away deep in forgotten memory and I am

unable to work it out, can anyone here guide me through so I can work

it out in the future if need be?

A google search tells me the formulas(?) are

Mg Citrate

C12H6Mg07.5H20

Zn Citrate

Zn3(C6H5)7)22.H20

Are these correct?

How much Mg/Zn per gram does that work out to be?

Thanks in advance,

Kelle

My Merck index says that magnesium citrate is C12H10Mg3O14, and is 16%

Mg. (The formula you have found is for magnesium citrate dibasic).

For zinc citrate, C12H10O14Zn3, 34 % Zn.

Thanks ,

I was told it was " easy " to work out how much in there if knew the

molecular weight of the formula. Do you know how to work it out? I

keep coming up with 7.6% for both of them: 3(Zn or Mg mols)/39 (the

total nr of mols)x100

This is way off yrs, how did you work it out? Or is that what the

Merck says?

Thanks,

Kelle

I got the percentages directly from the Merck index.

This is how to calculate.

Mg citrate = 451 g/mole, Mg = 24 g/mole

Mg citrate has 3 x Mg

3*24/451 * 100 = 16%

Zn citrate = 574 g/mole, Zn = 65 g/mole

Zn citrate has 3 x Zn

3*65/574 * 100 = 34%
