Question

if one mole of carbon atoms weighs 12 grams , what is the mass ( in grams) of 1 atom of carbon ?​

Answer 1

Answer:

Mass of one mole of carbon atom =12 g

A mole of carbon contains 6.022×1023 atoms.

Hence, mass of 6.022×1023 atoms of carbon =12 g

Mass of 1 atom of carbon =

6.022×10

23

12

=1.993×10

−23

g

Answer 2

Answer:

So, we know that a mole of carbon contains 6.022×1023 atoms. Therefore, we can write the mass of 6.022×1023 atoms = 12 g. Hence, the mass in grams of 1 atom of carbon is 1.993×10−23g .
