Molarity and molality of a solution of caustic soda are respectively ` 11.12 M ` and ` 94.12 m ` The density of the solution is

A

0.556 g `mL^(–1)`

B

5.56 g `mL^(–1)`

C

55.6 g `mL^(–1)`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
`d=M(1/m+"molar mass of value"/1000)`
`d=11.12(1/94.12+40/1000)`
= 0.556 g `mL^(-1)`
