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

Given, mass of 1 mole of carbon atom = 12 g

We know that 1 mole of carbon = 6.022 x 10²³ atoms

Therefore, mass of 6.022 x 10²³ atoms = 12 g

Hence,

Mass of 1 atom = $\frac{12}{6.022\times {10}^{23}}$

= 1.993 x 10^-23 g
