Answer 1

Answer on Question #81419, Chemistry/ Organic Chemistry

How many moles of diethyl ether are formed from 14 mil of ethanol?

Solution

$$2 \mathrm{CH_3CH_2OH} \xrightarrow{\mathrm{H_2SO_4}, t} \mathrm{CH_3CH_2OCH_2CH_3}$$ $$m = d \times V$$ $$m(\mathrm{CH_3CH_2OH}) = 14 \text{ mL} \times 0.789 \text{ g/mL} = 11.046 \text{ g}$$ $$n = m / M$$ $$n(\mathrm{CH_3CH_2OH}) = 11.046 \text{ g}/46 \text{ g/mol} = 0.24 \text{ mol}$$

According to equation 1 mole of diethyl ether is formed from 2 moles of ethanol

We have $x$ mole of diethyl ether which is formed from 0.24 moles of ethanol

Solve the proportion

$$\frac{1}{x} = \frac{2}{0.24}$$ $$x = 0.12$$ $$n(\mathrm{CH_3CH_2OCH_2CH_3}) = 0.12 \text{ mol}$$

Answer: 0.12 mol
