Question

Calculate the number of Cl2

molecules and Cl atoms in 0.25 mol of Cl2

gas.​

Answer 1

Answer:

we have ,

No. of mole of Cl2 molecule = 0.25 mol

Then, no.of Cl2 molecules = (0.25× 6.022× 10^23)

=. 1.5055× 10^23

Each Cl2 molecule contains 2 atoms of Cl.

Then, total no. of Cl atoms in 0.25mol cl2= (2×1.5055×10^23)= 3.011×10^23 Cl atoms
