Problem 89

Given information

A solution of    by mass has a density of  at  . A  sample of this solution is mixed with enough water to increase the volume of the solution to ^.

Step-by-step explanation

We can assume that, 

Mass of the solution is and mass of  is . 

So from this data we can calculate the initial molarity. And for that, we need to calculate the number of moles of solute of ,

Volume of solution is to be calculated to find initial molarity, and density is already  given
