Yep sure have. Have you ever had to determine that number experimentally? It’s quite revealing.

How did you go about doing it? Did you count the number of molecules?

I am done. Have fun.

“How did you go about doing it? Did you count the number of molecules?”

Obviously. Isn’t that what you do with a mole?

Acid sample 1, Acid sample 2

Crystal sample 1, Crystal sample 2.

Weigh both crystal samples. Measure volumes of both acid samples.

Add acid 1 to both crystal sample 1 and 2. Measure volumes needed to dissolve crystals.

Repeat with Crystal sample 1 and crystal sample two with acid sample 2.

Solve for the 4 variables and pray you don’t disturb the scale.
