Gce Model Questions Vol1 2024 Chemistry Question 2
Practice objective / multiple choice question 2 from the 2024 Gce Model Questions Vol1 Chemistry examination.
A 10.0 g sample of a mixture of ethanol (\(\mathrm{C_2H_5OH}\), M = 46.07 g mol⁻¹) and 2‑propanol (\(\mathrm{C_3H_7OH}\), M = 60.10 g mol⁻¹) is oxidised completely by excess acidified potassium dichromate. The oxidation consumes 29.4 g of \(\mathrm{K_2Cr_2O_7}\) (M = 294.19 g mol⁻¹). The masses of the oxidation products obtained are 0.66 g of acetic acid (\(\mathrm{CH_3COOH}\), M = 60.05 g mol⁻¹) and 9.2 g of acetone (\(\mathrm{CH_3COCH_3}\), M = 58.08 g mol⁻¹). Determine the mass of ethanol present in the original mixture.
