This means that the light gas particles are moving twice as fast, VH/VL = ½. Therefore, VH2/VL^2 = ¼. How many times heavier is the heavy gas compared to the light gas? VH = 51.12
VL = 19.45

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.

Which diagram shows the correct way to represent an ionic compound of magnesium oxide?

Which of the following represents the ester functional group? a. -coo- b. -cho c. -cooh d. c=o
