When most of the positively charged particles aimed at a piece of gold foil passed through it, but a few deflected or bounced back, Rutherford suggested that . an atom must consist of negative charges scattered throughout a ball of positive charge
electrons have almost no mass
electrons move in specific orbits around the nucleus of an atom
an atom’s positive charge must be clustered in a tiny region at its center

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.
