Question

If one mole of carbon atom weighs 12 g , what is the mass of 1 atom of carbon ?

Answer 1

1 mole of carbon contains = 6.022$\times$10²³ atoms
Molar mass of carbon = 12 g mol^​-1
Mass of 6.022$\times$10²³ atoms = 12 g
Mass of 1 atom of carbon = $\frac{12}{6.022\times {10}^{23}}$ = 1.99$\times$10^-23 g
