Question
Calculator the molality of an aqueous solution that is 48.0% by mass Ca(NO3)2
Expert Solution
Step 1: Introduction to the given data

Given data,

 an aqueous solution that is 48.0% by mass Ca(NO3)2..

i.e 100.0 g of the aqueous solution of Ca(NO3)2 contains 48.0 g of Ca(NO3)2.

Mass of water = 100 minus m a s s space o f space C a left parenthesis N O subscript 3 right parenthesis subscript 2 space equals 100 minus 48 space space equals space 52 space g

Molar mass of Ca(NO3)2 = 164.1 g/mol

The molality of an aqueous solution that is 48.0% by mass Ca(NO3)2 is
