For example: 1,3x10^21 is in scientific notation, but 13x10^20 is not in scientific notation.
Answer: 1.21x10²³ formula units Ca( ClO3)2
Explanation: solution attached:
Convert mass of Ca(ClO3)2 to moles
Convert moles of Ca(ClO3)2 to formula units using Avogadro's number
Answer:

Explanation:
Hello,
In this case, we work on a dilution process in which we can state that the moles remain the same after the dilution process. In such a way, we can write:

That in terms of molarities and volumes is:

Whereas
is the initial molarity (3.00 M) of the stock solution,
the molarity of the diluted solution (0.289 M),
the aliquot of the stock (concentrated) solution and
the volume of the diluted solution (100 mL), thus, we compute
as required:

Best regards.
