A sample with a mass of $63\,\text{g}$ of potassium manganate(VII), $\text{KMnO}_4$, is required to completely oxidise $23\,\text{g}$ of ethanol, $\text{C}_2\text{H}_5\text{OH}$, in acidic conditions. How many moles of ethanol are capable of being completely oxidised by one mole of potassium manganate(VII) under these conditions?
- A$0.37$
- B$0.80$
- C$1.00$
- D$1.25$
