Question

What is the Weight of a molecule of the compound C₆₀H_122?

Answer 1

So, the Molecule iS C₆₀H₁₂₂
Molecular mass of C₆₀H₁₂₂ --- [60x12+1x122]
=720+122
=842 Unified mass
Weight of one molecule of C₆₀H₁₂₂ :
=molecular weight of C₆₀H₁₂₂ / Avogadro's number
=842/6.023x10²³
=1.4x10⁻²¹ g

∴The weight of a molecule of a compound C₆₀H₁₂₂ is 1.4x10⁻²¹ g
