The rate constant for the decomposition of gaseous azomethane, CH3N=NCH3 ? N2 + C2H6 is 40.8 min-1 at a certain temperature. Calculate the number of moles of CH3N=NCH3 that have reacted in a 1.00 L flask 0.0500 min after 4.00 g of CH3N=NCH3 is introduced. The molar mass of azomethane is 58.0824 g/mol.
