If one mole of carbon atoms weighs 12 gram, what is the mass (in gram) of 1 atom of carbon?
One mole of carbon atoms weighs 12 g (Given)
i.e., mass of 1 mole of carbon atoms = 12 g
Then, mass of 6.022 x 1023 number of carbon atoms = 12 g
`"Therefore, mass of 1 atom of carbon "=12/(6.022xx10^(23))g=1.9926xx10^(-23)g`
