Answer:
Option D. 1.40x10^5g
Explanation:
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02x10^23 particles. This equally means that 1mole of Cl2 contains 6.02x10^23 particles.
1 mole of Cl2 =2 x 35.5 = 71g.
Now, If 71g of Cl2 contains 6.02x10^23 particles,
Then Xg of Cl2 will contain 1.19x10^27 particles i.e
Xg of Cl2 = (71x1.19x10^27)/(6.02x10^23)
Xg of Cl2 = 1.40x10^5g
Therefore, 1.40x10^5g of Cl2 contain 1.19x10^27 particles
