A solution was prepared by dissolving 155.0 gg of KClKCl in 305 gg of water. Calculate the mole fraction of KClKCl. (The formula weight of KClKCl is 74.6 g/molg/mol. The formula weight of water is 18.0 g/molg/mol.) Express the mole fraction of KClKCl to two decimal places. View Available Hint(s)

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or
