21 g of each Li (molar mass=7 g/mol) and N2 (molar mass=28 g/mol) are placed in a reaction vessel. What is the maximum mass of Li3N (molar mass=35) that can be produced
A similar question was asked before, but the formatting of the answer made it unreadable. So, I am asking it again. I have a thermodynamic system with three states in the canonical ensemble
