A 750 cm3\mathrm{cm^{3}}cm3 bottle of wine contains 69.0 g of ethanol. The bottle is left open and all of the ethanol is oxidised to ethanoic acid. Assume the volume of liquid does not change. (MrM_rMr: ethanol = 46, ethanoic acid = 60)
What is the final concentration of ethanoic acid?
1.13 mol dm−3\mathrm{mol\,dm^{-3}}moldm−3
1.50 mol dm−3\mathrm{mol\,dm^{-3}}moldm−3
1.53 mol dm−3\mathrm{mol\,dm^{-3}}moldm−3
2.00 mol dm−3\mathrm{mol\,dm^{-3}}moldm−3
