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

The moles of starting material is
`1.8212 * 10^(-2)` mole

Step-by-step explanation:

Given:

Cyclohexene oxide material is used

Density = 0.97
`(g)/(mL)`

Volume = 1.84 mL

Formula of Cyclohexene oxide =
`C_(6) H_(10) O`

Molar mass is given by,

`C = 6 * 12 = 72`

`H = 10 * 1 = 10`

`O = 1 * 16 = 16`

⇒
`m' = 96(g)/(mol)`

Mass
`m = 0.97 * 1.84 = 1.7848`
`g`

Moles is given by,

`n = (m)/(m')`

`n = (1.7848)/(98)`

`n = 1.8212 * 10^(-2)` mol

Therefore, the moles of starting material is
`1.8212 * 10^(-2)` mole
