Question

How many carbon atoms are present in 0.35 mol of C₆ H₁₂O₆ - 

(A) 6.023 × 10²³ carbon atoms 

(B) 1.26 × 10²³ carbon atoms 

(C) 1.26 × 10²⁴ carbon atoms 

(D) 6.023 × 10²⁴ carbon atoms

Answer 1

Correct option: (C) 1.26 × 10²⁴ carbon atoms

Explanation:

∴ 1 mol of C₆H₁₂O₆ has = 6 N atoms of C

∴ 0.35 mol of C₆H₁₂O₆ has = 6 × 0.35 N atoms of C

= 2.1 N atoms = 2.1 × 6.023 × 10²³ = 1.26 × 10²⁴ carbon atoms
