Question
The strength of 10-2 M Na2CO3 solution in terms of molality will be (density of solution = 1.10 g mL-1). (Molecular weight of Na2CO3 = 106 g mol-1)
Options
A.9.00 × 10-3
B.1.5 × 10-2
C.5.1 × 10-3
D.11.2 × 10-3
Solution
(A) Explanation : m = 
where ′m′ is molality, M is molarity.
= 9.00 × 10-3
[Take 1099.4 = 1100]
where ′m′ is molality, M is molarity.= 9.00 × 10-3 [Take 1099.4 = 1100]
