Answer :
Answer;
= 2.227 × 10^21 atoms
Explanation;
0.134 g of Cl
1 mole of Cl atom = 35.5 g
Moles of Cl = 0.134 g/35.5 g
= 0.003775 Moles
But; 1 mole = 6.02 × 10^23 atoms
Number of Cl atoms;
= 6.02 × 10^23 × 0.003775
= 2.227 × 10^21 atoms
= 2.227 × 10^21 atoms
0.134 g of Cl
1 mole of Cl atom = 35.5 g
Moles of Cl = 0.134 g/35.5 g
= 0.003775 Moles
But; 1 mole = 6.02 × 10^23 atoms
Number of Cl atoms;
= 6.02 × 10^23 × 0.003775
= 2.227 × 10^21 atoms
