For the following reaction grams of nitrogen monoxide are mixed with excess oxygen gas . The reaction yields grams of nitrogen dioxide .What is the theoretical yield of nitrogen dioxide grams What?

First, balance the equation: 2NO + O2 -> 2NO2 Calculate the molar mass of NO2 using the Periodic Table. Calculate the number of moles of NO involved using the given mass. Use the stoichiometry of the balanced equation to find the theoretical yield of NO2 in grams.
