Question

Assertion: The Relative Molecular Mass of Chlorine is 35.5 a.m.u.
Reason: The natural abundance of Chlorine isotopes are not equal.

i) A and R are correct, R explains the A.

ii) A is correct, R is wrong.

iii) A is wrong, R is correct.

iv) A and R are correct, R doesn’t explains A

​

Answer 1

Explanation:

hope it will help you bro

Answer 2

Answer:

option 1 is correct, A and R are correct and R explains A.

Explanation:

cl have 2 isotopes with mass 35 and 37 chlorine with 37 mass is less abundant then chlorine with 35 as its mass so so because of this the relative molecular mass of chlorine is is more shifted towards mass with 35 and when we calculate the relative mass of chlorine we get 35.5 AMU so assertion is correct and in the reason the natural abundance of chlorine isotopes are not equal yes they are not equal chlorine with mass 35 have more abundance than chlorine with 37 as mass.

Therefore, both A and R are correct and R explains A.
