Determine the volume of 02 (at STP) formed when 49.0 g of KClO3 decomposes according to the following reaction. The molar mass for KClO3 is 122.55 g/mol. Report your answer with
two (2) decimal places
2 KClO3(s) → 2 KCl(s) + 3 02(g)

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.
