Elenna [48]

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
