An aqueous antifreeze solution is 40.0% ethylene glycol (C2H6O2) by mass. The density of the solution is 1.05 g/cm3 . Calculate the molality, molarity, and mole fraction of the ethylene glycol.
Gen Chem Notes: Determining rate orders: For this experiment we will solve for the rate orders. To determine A, we will want to look for a spot where A changes but the value of B stays the same. Therefore, we may compare experiments 1 and 2. Between these experiments A doubles, while the rate quadruples. This means that A is a 2 order. To determine B we may do the same with experiments 2 and 3. In this we see that B doubles, but the rate does not change. This means that B is zero order, for if the rate does not change while the concentration does then it is zero order. Therefore, the total order of this reaction is 2, and the equation is rate = K [A]^2. Once one has solved
