Temperature dependence of solubility of gypsum and anhydrite

[Aksenova]

Hello
I've read Example 2 in the manual.
And I have a question.
It contains a code that shows the solubility of gypsum and anhydrite in distilled water.
A liter of water was taken and 1 mole of each substance was added.
1 mole of anhydrite has a mass of 136 g.
1 mole of gypsum has a mass of 172 g.
Could you tell me, based on the code results from the example (attached below), how many grams were dissolved and how many remained?
According to reference data, the solubility of these minerals is very low.

Code: [Select]

SOLUTION 1 Pure water
        pH      7.0
        temp    25.0               
EQUILIBRIUM_PHASES 1
        Gypsum          0.0     1.0
        Anhydrite       0.0     1.0

You will have to look at the output to see how many moles of a mineral dissolved. You can then calculate the number of grams.

Thank you. Got it.
