Question

If one mole of carbon atoms weighs 12g,what is the mass(in gram)of 1 atom of carbon

Answer 1

One mole of carbon atom weighs 12 gram. i.e. 6.022×10^ 23 atoms of carbon weighs 12 Gram. therefore, 1 atom of carbon weighs 12/ (6.022×10^23)=1.993 ×10-23 gram.

Answer 2

Answer:

One mole of carbon atoms=12g

In one mole the number of atoms=6.023*10^-23

So,

6.023*10^23 atoms =12g

1 atom =12/6.023*10^-23g

hope this helps you..
