Question

If one mole of carbon atoms weighs 12 grams, what is the mass (in grams) of 1 atom of carbon?

Answer 1

The mass of one mole Carbon= 12 grams

The mass of 6.022 × ${10}^{23}$ Carbon atoms = 12 grams

The mass of one atom of Carbon$=\frac{12}{6.022\times {10}^{23}}=1.993\times {10}^{-23}grams$
