1 mol of carbon-12 contains 6.022x10^23 carbon-12 atoms with a mass of 12 g. calculate the mass of one carbon-12 atom.

Question

1 mol of carbon-12 contains 6.022x10^23 carbon-12 atoms with a mass of 12 g. calculate the mass of one carbon-12 atom.

Answer 1

To calculate the mass of one atom, you would divide the total mass (12 g) by the number of atoms (6.022x10²³):

 

12 / 6.022x10²³ =

(12/6.022) * 1/10²³ =

1.993 x 10^-23 grams
