 the mass of a carbon atom is 1.994 x 10⁻²³ g
the mass of the carbon sample is 12.01 g
to find the number of Carbon atoms we have to divide the mass of sample by mass of a carbon atom.
number of C atoms = [tex] \frac{12.01 g}{1.994* 10^{-23}g } [/tex]
therefore number of atoms = 6.023 X 10²³ atoms of carbon
