A sample of carbon tetrachloride (CCI) contains 3 moles of the substance. How many atoms are there in the sample? O 1.806 x 1024
05
0 15
O 9.03 x 1024

Number of atoms =1.806×10²⁴

Explanation:

You have the number of moles of Carbon tetrachloride which is n=3

And you are looking for number of atoms that are in the sample, which are represented by the letter "N"

The formula that has both number of moles(n) and number of atoms(N) is written as n=N/Na

Na is called the Avogadros number and it is equal to 6.08×10²³, it never changes(it is a constant)

So you will substitute the number of moles and the avogadros number to you formula, and the only unknown will be the number of atoms which you are looking for

NB: N does not represent the number of atoms only. It may also represent the number of particles or molecules...

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
