Question

total number of chlorine atoms in 7kcl​

Answer 1

Answer:

6.022 x 1023

Explanation:

6.022 x 1023

Answer 2

Answer:

Given that

Mass of Cl2,W=7.1 g

Molar mass of Cl2,M=71g/mol

Number of moles x,=MW=70g/mol7.1g

 

                                   =0.1mol

Each Cl2 molecule contain 2 atoms.

∴ Number of Cl2 atom , N=2×n×NA

                                              =2×0.1×NA

                                               =0.2NA
