Question

calculate the no of atoms in 0.25 mole of SO2 ? (HINT- one molecule of SO2 contains 3 atoms)

Answer 1

Answer:

1.505x 10^23 atoms in 0.25 mol of SO2.

Explanation:

Number of atoms= avogadro's constant x number of moles

-Avogadro's constant= 6.02 x 10^23

-Number of moles= 0.25

(6.02 x 10^23) x 0.25= 1.505 x 10^23 atoms in 0.25mol of SO2.
