17.4 liters

c
21.2 liters

d
23.9 liters

Respuesta :

Answer:

23.9 liters

Explanation:

The total volume of the solution formed 23.9 liters.

What is volume?

The volume of a substance or thing is the quantity of 3D space it takes up. 

Calculation of volume with the aid of molarity is shown as:

Molarity = moles of solute / volume of solution in L.

Moles = mass / molar mass.

It is given that, molarity of NaCl = 0.0300 M

Mass of NaCl = 42 g

Molar mass of NaCl = 58,44 g/mol.

Moles of NaCl can be calculated as:

Moles of NaCl = mass of NaCl / molar mass of NaCl

= 42 g/ 58. 44 g/mol

= 0.719 mols.

Volume of NaCl can be calculated as:

Molarity = moles of solute / volume of solution in L.

0.0300 M = 0.719 moles/ Volume

Volume = 0.719 moles/ 0.0300 M

Volume = 23.97 L

Therefore, the volume will be 23.97 L.
