Raoult's Law, Finding an unknown compound
1. A 1.00m aqueos solution of compound X had a boiling point of 101.04 Celsius. Which one of the following could be compound X? The boiling point elevation constant for water is 0.52
1: identify the change in bp temperature. in this case, it's 101.04-100 = 1.04 degrees C.
2. divide this change by your bp elevation constant. 1.04/0.52 = 2
so now I think that means that two different molecules were added. My guess is it was KCl (potassium chloride). but of course, I'm not entirely sure =/
Can someone help me out?
1. The problem statement, all variables and given/known data
2. Relevant equations
3. The attempt at a solution
