2.4 moles in of NO 2.4 moles of O2 and 2.4 moles of h2o react and 2.0 moles of HNO3 are recovered from the reaction what is the percent yield of this reaction

Does anyone know a lot about how to: - calculate mass of magnesium metal - calculate the actual yield of magnesium oxide - calculate the theoretical yield of mgo - calculate the percent yield of mgo - determine the percent yield of mgo - determine the average percent yield of mgo i had to do an online lab and its asking these questions but i have no idea where to start or how to be able to find these things. i can post the chart of the data from the lab or if you can tell me exactly how i can find each.

How many moles of magnesium is 3.01 x10^22 atoms of magnesium?
