[Math Processing Error]

Explanation:

To calculate the density of the solution, we have to use the formula below:

[Math Processing Error]

  • Usually, density will have units of [Math Processing Error] when dealing with a liquid or units of [Math Processing Error] when dealing with a solid.

  • The mass has units of grams, [Math Processing Error].

  • The volume can have units of milliliters, [Math Processing Error]

Let's determine the mass of the solution:

Mass of solution = mass of solute + mass of solvent

[Math Processing Error] [Math Processing Error]= 73g

( I used the density of water, 1 g/mL, to determine the mass of solvent.)

The mass of solute (23 g) is already given, so we add the two values together to obtain the mass of the solution:

[Math Processing Error]

Now, we need the volume of solution:

Volume of solution = volume of solute + volume of solvent:

[Math Processing Error] [Math Processing Error] = 10.62 mL

( I used the density of table salt, 2.165 g/mL, to determine the volume of the solute)

The volume of solvent (73mL) is already provided, so the total volume of the solution is:

[Math Processing Error]

Divide the mass of the solution by the volume of the solution to obtain the density:

Density = [Math Processing Error] = 1.1 g/mL
