Greetings,
I'd be happy to show you an easy method for solving these and all other stoichiometry problems or empirical formula problems using your units and creating a tangible concept map for problem solving. Feel free to contact me and we can get started as soon as possible. 1 mol of Mg in this reaction yields 2 mol of MgO.
