3.00 g of the hydrate CoCl2.xH2O was heated and after the water was driven off, 1.64 g of CoCl2 remained. (Use these atomic masses: Co = 59 Cl= 35.5 H = 1 O =16 ) You are required to find x by following the steps outlined below.
Find the following:
a. The mass of water driven off
b. The number of moles of H2O driven off
c. The number of moles of CoCl2 formed
d. The number of moles of H2O divide by the number of moles of CoCl2 = x (write as a whole number)
e. The full formula of the hydrate

First up write the aim
then write the materials reqd.
then the procedure which you follow
then observation
then conclusion
then you can write lab safety rules or precautions(you can avoid if u want).
lemme' give an example
aim: to observe the double displacement reaction
materials reqd: bacl2 and na2so4, test tubes and a dropper
procedure:
1. take bacl2 in a test tube and na2so4 in the other.
2. then pour bacl2 into na2so4 solution.
3. observe
observation:
you will see that a white precipitate is formed called baso4. along with that common salt or nacl is formed.
the equation is
bacl2+na2so4=baso4+2nacl
conclusion:
a double displacement reaction is observed.
hope it

The answer would be solvent
