How many atoms of carbon are in 24 grams of carbon?
a) 1.2 x 10²⁴ atoms
b) 1.7 x 10²⁶ atoms
c) 1.2 x 10²⁵ atoms
d) 3.0 x 10²⁴ atoms
e) 3.0 x 10²³ atoms

Can anyone explain this one?

Sagot :

(3 grams of carbon) x (1 mole of carbon/12 grams ) =3/12 = 1/4 of a mole of carbon. Then... ( 1/4 of a mole) x (6.02 x 10^23 atoms/mole) = approximately 1.5 x 10^23 atoms.
