Answer:

77%

Explanation:

First we convert 3.0 g of cyclohexanol (C₆H₁₂O) to moles, using its molar mass:

  • Molar mass of C₆H₁₂O = 100.158 g/mol
  • 3.0 g ÷ 100.158 g/mol = 0.030 mol

Then we convert 1.9 g of cyclohexene (C₆H₁₀) to moles, using its molar mass:

  • Molar mass of C₆H₁₀ = 82.143 g/mol
  • 1.9 g ÷ 82.143 g/mol = 0.023 mol

Finally we calculate the theoretical yield:

  • 0.023 mol / 0.030 mol * 100% = 77%
