Question

which of the aqueous solutions have the highest boiling point
a)0.20 m glucose
b)0.10 m Na2SO4
c)0.25 m sucrose
d)0.10 NaCl

Answer 1

Hey buddy here is ur answer =

here the answer is option <b>

..it has highest boiling point.

Supposing complete ionization: 

Na2SO4 → 2 Na{+} + SO4{2-} [three ions total] 

(0.10 m Na2SO4) x (3 mol ions / 1 mol Na2SO4) = 0.30 m ions 

(0.30 m) x (0.512°C/m) = 0.1536°C change 

100°C + 0.1536°C = 1000.15°C

hope it helps!

happy weekend

Answer 2

Answer:

But molality is already given then why we are calculating molaity again
