ANSWER:

Problem 108P

A  solution is made using 88.4 g of  and diluting to a total solution volume of 1.50 L. Calculate the molarity and mass percent of the solution. (Assume a density of 1.05 g/mL for the solution.)

                       

                                                               Step by Step Solution

Step 1 of 3

Moles of  can be calculated by the following formula.

.............(1)

From the given,

Mass = 83.4 g

Molar mass = 101.103 g/mol

Substitute the values in the equation (1)

Hence, 0.825 mol of  is present in the  1.5 L.
