Try it on paper first. A hint, the key idea and the worked solution are here when you need them.

A plant passes ethene and steam over a phosphoric acid catalyst. The mixture is recycled, and the overall yield of ethanol is $95\ \%$ of the ethene fed in. The plant feeds in $140.0\ \text{kg}$ of ethene. Use $28.054\ \text{g/mol}$ for ethene and $46.069\ \text{g/mol}$ for ethanol. Find the amount of ethene in kmol, the amount of ethanol produced in kmol, and the mass of ethanol in kg.

Need a reminder? The key ideaShow

Acid hydration puts OH on the more substituted carbon. Hydroboration then oxidation puts it on the less substituted carbon, and one BH $_3$ takes three alkene molecules. NaBH $_4$ reduces four C=O groups for each formula unit. A Grignard reagent adds its R group to the carbonyl carbon. Yield $= \dfrac{\text{actual}}{\text{theoretical}} \times 100$ .

The worked solution

Have you tried it?

Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
