6NO2+2H2O=4(HNO3)+2NO. For this equation, how many grams of nitrogen dioxide are needed to react with 3.70mol of H2O? How many grams of nitrogen monoxide are produced when 2.18mol of H2O react? If 60 grams of H2O and 85 grams of nitrogen dioxide are available, how many grams of nitrogen monoxide can be produced?
