Question

Can someone tell me if I'm doing this wrong?
Formula Of a Hydrate....

Answer 1

@abb0t @nincompoop

Answer 2

first - yes correct
second one
hmm
the formula is
\[\sf \frac{ mass~of~solute }{ mass~of~solution } \times 100\]
your mass of solute would be mass of anhydrous salt
and mass of solution would be mass of hydrated salt (which is mixture of water and anhydrous salt)

Answer 3

wait a sec

Answer 4

yep you are correct in second one too :3
good job!!

Answer 5

i didnt notice the 'of water' part hehe :P

Answer 6

oh ok thanks :) so how would i find the mole ratio of anhydrous salt to water?

Answer 7

I did 0.053 mol H2O/0.0033 = 16
0.0033 mol CuSO4 / 0.0033 =1
but i dont think thats right

Answer 8

it seems to be correct to me
if the q is saying 'mole ratio OF water TO anhydrous salt' would be water/anhydrous salt

Answer 9

your salt is CuSO4?

Answer 10

hmm ok can i ask you one more question? :D

Answer 11

sure :)

Answer 12

never mind, i figured it out :) thanks @Somy

Answer 13

no problem :))
