Question

How many atoms are contained in one mole of sucrose (C₁₂H₂₂O₁₁) 

(A) 45× 6.023 × 10²³ atoms/mole 

(B) 5× 6.623 × 10²³ atoms/mole 

(C) 5× 6.023 × 10²³ atoms/mole 

(D) None of these 

Answer 1

45× 6.023 × 10²³ atoms/mole atoms are contained in one mole of sucrose (C₁₂H₂₂O₁₁) .

Explanation :-

1 mole of sucrose contains 

6.023 × 10²³ molecules 

∵ 1 molecule of sucrose has 45 atoms 

∴ 6.023 × 10²³ molecule of sucrose has 

45 × 6.023 × 10²³ atoms/mole
