Asked by Hannah
After performing a freezing point depression experiment I had to find the molecular weight of glycol. Now I have to answer the question what value did I assume "i" to equal and why did I make this assumption.
My teacher told us the value of i to use for this was 1. I am not sure why though. Could someome please explain. Thank you for your help!!

Ethylene glycol does not ionize; remember i is the number of particles. NaCl has two when dissolved in water so i = 2. But ethylene glycol doesn't ionize. You get 6.02E23 particles when you dissolve a mole of ethylene glycol. When you dissolve a mole of NaCl you get 2*6.02E23 particles.
