Question

Carbon tetrachloride contains one carbon and four chlorine atoms. for this compound 11.818 g of chlorine combine with 1.000 g of c-12. using this information, calculate the atomic mass of chlorine.

Answer 1

12000 I iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii

Answer 2

Atomic mass of Cl = 35.46 g/mol

Step-by-step explanation:

From the given information:

Carbon tetrachloride
`CCl_(4)` contains one carbon (C) and for chlorine (Cl) atoms

11.818 g of Cl combines with 1.000 g of C-12

Moles of C :

=
`(Mass\ C)/(Atomic\ Mass) =(1.000g)/(12g/mol) =0.0833moles`

Molar ratio of C:Cl = 1:4

Therefore, moles of Cl is:

`4(0.0833) = 0.3332moles`

Atomic mass of Cl is:

`(Mass\ Cl)/(moles\ Cl) =(11.818g)/(0.3332moles) =35.46 g/mol`
