Question

how much times an atom of mg and chlorine will be heavier than carbon 12​

Answer 1

Explanation:

The atomic weight of carbon is 12 and that of chlorine is 35.55≈36 which is 3 times of at.

Answer 2

Answer:

molar mass of mg is 24g

molar mass of cl is 35.5

{ an easy way to understand this is maths tables

 we know, 2 times 2 is 4 i.e... 2*2=4

similarly in this case-  x times 12=24

                                   x times 12=35,5}

x*12=24

x=24/12

x=2

therefore mg is 2 times heavier than carbon 12.

for cl:

x*12=35.5

x=35.5/12

x=2.95833333333{ which is approx 3)

therefore cl is approximately 3 times heavier than carbon 12
