Best answer

Number of moles = n

Given mass = m

molar mass = M

Given number of particles = N

Avogodro number of particles = N0

Atomic mass of carbon = 12u.

Atomic mass of one mole of carbon = 12g

But Atomic mas of carbon = 12 g mass of 6.022 × 1023 carbon atoms = 12g.

\(\frac{12}{6.022\times 10^{23}}\) gms

∴ Mass of carbon atoms

= 1.9926 x 10-23 gm.
