The weight of one molecule of a compound C₆₀H₁₂₂ is
Options
(a) 1.2 x 10⁻²° gram
(b) 1.4 x 10⁻²¹ gram
(c) 5.025 x 10²³ gram
(d) 6.023 x 10²³ gram
Correct Answer:
1.4 x 10⁻²¹ gram
Explanation:
Atomic Mass of C=12
Atomic Mass of H=1
Molecular Weight of C₆₀H₁₂₂ = 12 x 60 + 122 = 842
Weight of 1 molecule = Mol Wt of C₆₀H₁₂₂ / Avagadro No
=842 / 6.023 x 10²³ = 1.4 x 10⁻²¹ g
