Question

1. True or False. 2.0 m KI has the same boiling point as 2.0 m NaI. And true or false. Osmotic pressure pushes solvents towards regions of high salt concertations? 3. When you buy liquor that's marked 12% ABV, how much pure alcohol is consumed when you drink 100.0 mL?

Answer 1

1) 2.0 m KI has the same boiling point as 2.0 m NaI ( False )

explanation : boiling point depends on intermolecular forces strength . here both have same concentration .

but NaI lattice energy is more than KI lattice energy .so NaI boiling point is more than KI boiling point

2) Osmotic pressure pushes solvents towards regions of high salt concertations (True)

osmosis means the movement of sovlent particles from low concnetration to high concentration . or pure solvent to solution .

here the above statement is given correctly .

3)

12% ABV means 12 mL alcohol in 100 mL solution .

ABV = alcohol by volume

so alcohol consumed = 12 mL
