If one mole of carbon atom weigh 12 grams. What is the mass ( in grams) of 1 atom of carbon?

Explanation

Molar mass (M) of carbon atom = 12 g
Number (N) of particles (atoms) = 1
Avogadro.s number `(N_(0)) = 6.023 xx 10^(23)`
Given mass = `("Number of particles" xx " Molar mass")/("Avogadro.s mass")`
`implies m = (N xx M)/(N_(0))`
`implies m = (1 xx 12)/(6.023 xx 10^(23))`
`implies m = 1.99 xx 10^(-23)` g
