Question

Molarity and molality of an aqueous solution (mol. wt. of solute = 50) is 9 and 10 respectively. The
density of solution will be
(1) 1 g/cc
(2) 0.95 g/cc
(3) 1.05 g/cc
(4) 1.35 g/cc​

Answer 1

Answer:

1

Explanation:

M=n/V(l). m= n/ kg(solvant)

if we divide both than n will be cancelled

M/m= 1/V/1/kg

9/10= 50/V

V= 500/9

= 55.55

density = mass / volume

50/55.55

= 0.900
