Could someone please help me answer these two questions?
1.  To change the freezing point of water from 32 degrees F to 31 degrees F, how many PPM of nitrates need to be added?
2.  If the normal freezing point of water is 32 degrees F, with 15, 30, and 60 PPM of nitrates added, what would that change in temperature be?
Please don't think that by answering these questions, you're doing my homework for me.  I'm 1 year out of college and this is for general knowledge.  Thanks so much!

Is there actually a formula to calculate how melting and freezing points change with the addition of different salts?
