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

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

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.
