Homework Statement
Okay so I received this lab called Determining the Chemical Formula of a Hydrate, but I was not there to do it with my group..but I still had to answer these two questions. I was wondering if someone could help me answer them? >< Or explain?! ><
CuSO4 . xH2O
Materials:
400ml Beaker
tongs
scoopula
electronic balance
hot pad
3 g to 5 g hydrated copper sulfate
QUESTIONS I NEED HELP ON
8. Suppose the hydrate was heated too quickly and some of it was lost as it spattered out of the container. Explain how this would affect
a) The calculated percent by mass of water in the compound. Does the mass/percent increase? What?!
b) The molecular formula you determined..CuSO4 5H20? O_O
9) Suggest a source of errot that would result in a value of x that is
a) higher than the actual value (How would it affect...like...a negative or something in the value of X? )
b) lower than the actual value.
PLEASE AND THANK YOU! I need a reply please by tomorrow? ): ITS DUE THEN
THANKS
