Question
The number of atoms in 0.1 mole of a tri atomic gas is (NA = 6.02 × 1023 mol-1)
Options
A.6.026 × 1022
B.1.806 × 1023
C.3.600 × 1023
D.1.800 × 1022
Solution
Number of atoms = number of moles × NA × atomicity
= 0.1 × 6.02 × 1023 × 3
= 1.806 × 1023 atoms
= 0.1 × 6.02 × 1023 × 3
= 1.806 × 1023 atoms
