Convert Mg to grams
1g =1000mg what about 3.91 Mg
= 3.91mg x 1g/1000mg= 3.91 x10^-3 g
moles= mass/molar mass
that is 3.91 x10^-3g /99 g/mol=3.95 x10^-5moles
concentration= moles / vol in liters
that is 3.95 x10^-5/100 x1000= 3.94 x10^-4M
equation for dissociation of CUCl= CUCl----> CU^+ +Cl^-
Ksp=(CU+)(CI-)
that is (3.95 x10^-4)(3.95 x10^-4)
Ksp= 1.56 x10^-7
Options:
conduct an experiment
form a hypothesis
draw a conclusion
state the cause
Answer:
'<u>State the cause'</u> is not part of the scientific method.
Explanation:
The scientific method has three wholistic steps:
- Test the hypothesis
- Make observations from the experiment to the hypothesis
- Draw a conclusion or prediction from the experimental results.
A cause is neither a scientific term nor is it part of the processes of experimentation.
