The coolant in automobiles is often a 50/50 % by volume mixture of ethylene glycol, c2h6o2, and water. at 20°c, the density of ethylene glycol is 1.1088 g/ml and the density of water is 0.9982 g/ml. what is the expected freezing point of a 50/50(v/v)% ethylene glycol/water solution? kf = 1.86°c/m for water.

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.
