Ijmb Model Questions Vol1 2017 Chemistry Question 2
Practice practical question 2 from the 2017 Ijmb Model Questions Vol1 Chemistry examination. This question covers Periodic Table, Stoichiometry .
A 0.250 g sample of an unknown metallic solid was placed in a conical flask containing excess dilute hydrochloric acid. The hydrogen gas produced was collected over water at 25 °C. The volume of gas collected was 112 mL. Atmospheric pressure was 760 mm Hg and the vapour pressure of water at 25 °C is 23.8 mm Hg. Assume the metal reacts according to M + 2HCl → MCl₂ + H₂ (1 mol metal : 1 mol H₂). Using the data, determine the atomic mass of the metal and identify the element from the periodic table.
