Question

While performing the Acid-catalyzed Hydrolysis of Epoxides experiment you used a solution containing 1.84 mL of cyclohexene oxide. After the reaction was completed and worked up, you obtained 0.739 g of 1,2-cyclohexane diol. Calculate the moles of starting material used.

Answer 1

Answer:

The moles of starting material is $1.8212 \times 10^{-2}$ mole

Explanation:

Given:

Cyclohexene oxide material is used

Density = 0.97$\frac{g}{mL}$

Volume = 1.84  mL

Formula of Cyclohexene oxide = $C_{6} H_{10} O$

Molar mass is given by,

$C = 6 \times 12 = 72$

$H = 10 \times 1 = 10$

$O = 1 \times 16 = 16$

⇒ $m' = 96\frac{g}{mol}$

Mass $m = 0.97 \times 1.84 = 1.7848$ $g$

Moles is given by,

  $n = \frac{m}{m'}$

  $n = \frac{1.7848}{98}$

  $n = 1.8212 \times 10^{-2}$ mol

Therefore, the moles of starting material is $1.8212 \times 10^{-2}$ mole
