This is related to a biology issue. I am preparing media for cell culturing, and I need to measure out a lot of salts in very exact amounts. Sometimes, the recipe requires a salt with a certain water of hydration, and the salt which I have in my disposition has a different water of hydration.
So I tried to devise a formula to enable me to quickly convert the grams of salt.xH2O into grams of salt.yH2O
Since sometimes I struggle with numbers, I would really appreciate if someone checks it out.
Grams of salt.yH2O = [Grams of salt.xH2O X (Molar mass of salt y)2] / (Molar mass of salt x)2
Thanks
