Gce Model Questions Vol1 2017 Chemistry Question 23
Practice objective / multiple choice question 23 from the 2017 Gce Model Questions Vol1 Chemistry examination.
A 2.00 g mixture of ethanol (\(\mathrm{C_2H_5OH}\), \(M = 46.07\ \mathrm{g\,mol^{-1}}\)) and isopropanol (\(\mathrm{C_3H_7OH}\), \(M = 60.10\ \mathrm{g\,mol^{-1}}\)) reacts with excess sodium metal. The reaction produces \(0.45\ \mathrm{L}\) of hydrogen gas at STP. If the mass of ethanol is twice that of isopropanol, calculate the mass percent of ethanol in the original mixture.
