Question

will medal!!

Which of the following solutions would have the lowest boiling point?

1.0 M NaCl
2.0 M NaCl
3.0 M NaCl
4.0 M NaCl

Please explain too! :(

Answer 1

1/A The more that is dissolved in water, the higher it boils. ^^

Answer 2

and how do I figure out how it dissolves in water?

Answer 3

"This is because a lower molarity solution will have a lower vapor pressure and solutions don't boil until the vapor pressure of the solution is equal to atmospheric pressure. So the Lower the vapor pressure, the lesser amount of energy/heat is needed to reach boiling point." :)

Answer 4

I finally understand!! thank you so much :)))
