The number of atoms in 0.1 mol of a triatomic gas is ( A N =6.022×10 ) (CBSE AIPMT 2010)
A.6.026 × 1022
B.1.806 × 1023✓ Correct
C.1.800 × 1022
D.3.600× 1023
Explanation
Given, Avagadro number ( A N ) = 23 6.023 10 x 1 mol of a compound contains 1 Avogadro number of molecules Then 0.1 moles of compound contains 22 6.022 10 x molecules ---- (1) Number of atoms in one triatomic molecule = 3--- (2) Therefore, the number of atoms in 0.1 moles of a triatomic gas = 22 22 23 6.022 10 3 18.066 10 1.8066 10 atoms x x x x
