Step 1

Density is a physical quantity that can be determined with the help of the mass and volume of the given substance.

The formula of the density of any substance can be written as:

Step 2

a) Calculate the mass of solution in 1.000 L

Density of solution = 1.67 g/mL

1.000 L  =  1000 mL

Hence the mass of 1.000 L solution:

Step 3

b)  Calculate the mass of acid in 1.000 L of solution:

Weight percent of a solute is equal to the mass of the solute divided by the t...
