Question

Since people aren't helping me in the chemistry section, mathematics is my second best choice to post this...
What mass of KCl would be needed to form a saturated solution if the KCl was
dissolved in 200 g of water at 80 °C?

Answer 1

I need help... Really. I need to get this done

Answer 2

its best to post it in chem, and then come to math chat with a link to your question to draw people to it.

not sure how mathy an approach would be unless you know some formulas or properties related to this

Answer 3

saturation is the point where no more is dissolved .... but other than that i got nothing

Answer 4

Look buddy... no one is noticing my question on the chemistry page and I need help...

Answer 5

im not your buddy .... im a moderator of this site. unless you know of a mathy approach to this then keep it where it belongs.

Answer 6

do you know any dissolution formula?

Answer 7

??? Okay....
This has math in it...js

Answer 8

What is that?

Answer 9

i cant find anything i can actually read and understand about this on google.

something about Ksp or aqueous stuff ... sorry, its greek to me.

Answer 10

Uggghh.... I guess I'll just take it down. This really sucks cause I need help with this..

Answer 11

yeah, i cant make sense of any of it from the google .... any approach i try to think of would just be a wild guess.

good luck tho

Answer 12

Look for KCl in the water solubility table on wikipedia here:

http://en.wikipedia.org/wiki/Solubility_table#P

find the solubility for 80deg.

the solubility is given in g/kg i.e. ___ g of KCl in 1 kg of H2O. then solve for ur ans.

good luck!

Answer 13

Oh thank you !!!
