Question

What is the molality of C,H,OH in water solution
which will freeze at -10°C? [Mol. wt. of C,H,OH
= 46, K, for water = 1.86]
(1) 6.315 m
(2) 63.15 m
(3) 3.540 m
(4) 5.3 m​

Answer 1

Answer:

morality ot a solution may be define as the total no of gram moles of solute dissolved per kg of solution. it is denoted by m

Answer 2

Answer:

0-(-10)=1.86×m

m=10/1.86

m=5.3m
