Mass lost in dehydration? (Chemistry HW)?

Find the % mass loss you would expect if ALK(SO4)2*nH2O were fully dehydrated.

We dehydrated aluminum potassium sulfate, and I need to predict what mass was lost due to the water evaporating.

Thanks in advance! :]

She takes more salt than anyone I know and if she is eating chips she salts each layer liberally. She cannot eat food without salt. Could this have contributed?

How is lithium sodium and potassium originally stored?

I’ve been having these symptoms:

Bad spots
Feeling queasy
Erotic dreams
Abnormally light periods
Feeling of pressure (not painful or itchy) around vulva

I have had an STD test and it was clear. Pregnancy test was negative. Today I had my blood pressure taken and it was abnormally high (153/105).

Anyone have any ideas as to what could be causing those symptoms?

Dehydration of sugar by conc. Sulfuric acid

It is very common reaction which demonstrates the dehydrating and oxidizing properties of conc. Sulfuric acid. Sugar is first dehydrated to elemental Carbon and steam, Carbon is further oxidized to Carbon dioxide, sulfur dioxide also produced by reduction of SO4 2-.

In blood tests, what’s the code for potassium?

Is it true that the result for potassium in blood tests is listed under the letter ‘K’?

What is the code ‘CK’ referring to?

This is because I always feel very tired and I’ve been told that it might be a potassium deficiency.

Is it possible to get potassium supplements over the counter without prescription?

I thank you for any extra information you might want to give me.
