Refer to the balanced equation below and answer the following questions?
2NO (g) + O2 (g) ----------> 2NO2 (g)
1. How many moles of O2 is required to react completely with 3.50 mol of NO?
2. How many grams of NO is required to react with 6.37 grams of oxygen gas?
3. If you react 40.00 grams each of NO and O2, how many grams of NO2 will form?
4. After you performed the experiment as in above, you obtained 30.22 grams of NO2. What is the percent yield?
