Question

The weight of one molecule of a compound C₆ₒH₁₂₂ is
(a) 1.2x10⁻²⁰ gram (b) 1.4x10⁻²¹ gram
(c) 5.025x10²³ gram (d) 6.023x10²³ gram

Answer 1

Answer:

d is the answer of question

6.023×10²³

Answer 2

(b) 1.4x10⁻²¹ gram

Explanation:

Weight of one mole of C₆ₒH₁₂₂ = (60 * 12) + (122 * 1) = 842

Number of molecules in 1 mole = 6.023 * 10^23

So weight of one molecule of C₆ₒH₁₂₂ = 842/(6.023 * 10^23) = 1.4 * 10^-21

Option B is the answer.
