How many atoms are there in 1 gram of carbon?

For  calculation of number of atoms we have to

  1. calculate the number of moles present in 1gram carbon.
  2. Multiply the number of moles with Avogadro number.

Step I

 Number of moles in 1 gram of carbon = given mass / molar mass

Molar mass (molecular or atomic mass expressed in grams) = 12g

So the number of mole= 1/12

                               = 0.0833 moles

Step II

1g of carbon will have = 0.0833 x 6.022 x 1023  

= 0.501 x 1023

1 gram of carbon will have = 5.01 x 1022   atoms
