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

C) C6H12O6


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
