Question #5ab50
1 Answer
Answer:
Explanation:
To calculate the density of the solution, we have to use the formula below:

Usually, density will have units of
#g/(mL)# when dealing with a liquid or units of#g/(cm^3)# when dealing with a solid. 
The mass has units of grams,
#g# . 
The volume can have units of milliliters,
#mL#
Let's determine the mass of the solution:
Mass of solution = mass of solute + mass of solvent
( 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:
Now, we need the volume of solution:
Volume of solution = volume of solute + volume of solvent:
( 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:
Divide the mass of the solution by the volume of the solution to obtain the density:
Density =
