Question

Chemistry :c

Answer 1

The experiment is done on Latenitelabs, the email address to get in isss kbecker@avmi.org and the password is day11. And the experiment is Empirical Formula For a Hydrate.

I don't need just answers but something would be amazing. Because I'm honestly just lost. I have 3 projects to do today and I'll be completely done with Chemistry.

Answer 2

you have the reading?

Answer 3

It's spread over a few lessons. I can give you my school info if you want? They didn't cover it extremely well, though.

Answer 4

i cant help you with masses of the compounds, i can with what you have do after you have the masses, the logic!

Answer 5

I need to learn a lot of Chemistry. T_T

Answer 6

Okay. I can get the basic masses easy enough. I don't know how to multiply them together and get the stuff after that.
@ParthKohli It is hell.

Answer 7

Nah, I'd just stick to Math, hehe.

Answer 8

Argh. I don't wanna fail :c

Answer 9

look, find the moles of cuso4 and h2o. just divide the observed mass with molecular mass. now you have to find number of moles of water(X), that 1 mole of cuso4 would furnish, that should be easy. plug X and you have the formula.

Answer 10

omg I'm going to fail. Flipping chemistry.

Answer 11

lol. its really easy. you need to calm down, and you'll get it.

Answer 12

I don't even know how to find the moles. It's seriously I wonder I even have a C in Chemistry. That and projects count for 40% of my grade :/

Answer 13

divide observed mass by molecular mass. molec. mass of cuso4 is 160 and h2o is 18. so moles of cuso4 are w1/160 and moles of h20 are w2/18.

Answer 14

How do you know this stuff? o.o
anddd am I dividing 160 by the 18?

Answer 15

Now I am feeling like an idiot.

Answer 16

Me too

Answer 17

lol. i know this.. let w1/160=moles of cuso4 be Y and moles of water=Z.
once you have these two values, divide Z/Y. this would give you X, i.e number of moles of water for 1 mole of copper sulphate.
