Question

how many no. of molecules in 35.5 g of chlorine​

Answer 1

Answer:

Since, 1 mole of Cl2 has Avagadro number of molecules

Therefore, 35.5 g = 0.5 moles

Then, Number of molecules => 0.5 × 6.02 × 10^23 => 3.01 × 10^23

Hence, there is 3.01 × 10^23 molecules in 35.5 g of chlorine.

Explanation:

HTH!¡! :)

Answer 2

Since 35.5 g is the mass of one mole of chlorine, So we have 6.022 × 10^23 molecules of the chlorine gas. Since chlorine gas is diatomic (Cl2), there are 2×6.022 × 10^23 =1.204×10^24 atoms of chlorine in the 1 mole.
