convert Cacl2.6h20 to cacl2.2h20


Hello

If i have a chemical formula :
27% Cacl2.6h20
43 % hso
30% balance a mix of chemicals

How do i convert this formula to % ;)Cacl2.2h20 and H20 ?
The molecular weights are as follows :

Cacl2. 6h20
% Cacl2 = 50.66
% h20 = 49.34

Cacl2.2h20
% Cacl2 = 75.49
% h20 = 24.51

Please help me if you can. Many thank yous Jane ;)

This reeks of being a homework question, and it looks like you haven't put much effort into it. First of all, use proper capitalization, Cacl2 != CaCl<sub>2</sub>(Using subscripts goes a long way too). Similarly, H20 != H<sub>2</sub>O. Show the work that you have done so far. What approaches have you tried/how far have you gotten?

Boil it down while weighing it periodically? I'm not clear on what you mean by "hso". H2O?

I might have given a link to the FAQ, and made a statement regarding asking US to just do your homework for you, vs. asking us questions related to YOU understanding that homework.

I mean, that was a first post. Whoever it was never made another one.

Rapopart’s Rules for critical commentary:

1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.

Anatol Rapoport was a Russian-born American mathematical psychologist (1911-2007).
