Find the number of atoms in the following:
(i) 0.5 mole of C atom
(ii) 2 mole of N atom

Academic Chemistry NCERT Class 9

(i) 0.5 mole of C atom:

Number of atoms in 1 mole of C atom = 6.022 x 10²³ atoms

Number of atoms in 0.5 mole of C atom = 6.022 x 10²³ x 0.5

= 3.011 x 1023 atoms

(ii) 2 mole of N atom:

Number of atoms in 1 mole of N atom = 6.022 x 10²³ atoms

Number of atoms in 2 mole of N atom = 6.022 x 2 x 10²³

= 1.2044 x 10²⁴atoms .
