Answer 4

You just need to compare the number of ions the substance breaks up into. How many ions come from NaCl? How many from CaCl2?

The more ions there are, the higher the boiling point.

Answer 5

How do you know the number of ions? @agent0smith

Answer 6

Look at the formula. How many ions are there in a single NaCl? Or a single CaCl2

Answer 7

how do you find the ions?

Answer 8

Answer 9

Look at NaCl. How many Na's are there in the formula? How many Cl's?

Answer 10

1 Na 1Cl

Answer 11

@agent0smith

Answer 12

Yes. So how many ions total in NaCl?

Now do CaCl2
