Gases: 1. You are studying the following reaction: 14 Mg(s) + 2 HBr(aq) → MgBr2(aq) + H2(g) You add 0.8879 grams of Mg to excess HBr solution to form H2 gas. You collect the H2 gas over water at 40°C and find that you have 1.431 atm of gas. Assuming 100% yield for the reaction, what is the volume of the H2 gas collected? Note: The vapor pressure of water can be neglected. Molar masses: Mg = 24.31 g/mol MgBr2 =184.11 g/mol HBr = 80.91 g/mol H₂ = 2.016 g/mol ZO
