Answer: The volume of the solution formed will be 32.5 L. Explanation: Molarity is defined as the amount of solute present in 1 L of solution. The equation used to determine molarity of the solution follows: We are given: Molarity of the solution = 0.02 mol/L Mass of NaCl = 38 grams Molar mass of NaCl = 58.5 g/mol Putting values in above equation, we get: Hence, the volume of the solution formed will be 32.5 L.
The total volume of the solution will be 21.66 L
What is solution?
A solution is a uniformly dispersed mixture of more than one solute in a solvent. The type of substance under which a solute is dissolved to form a homogenous mixture is called a solvent. The substance that dissolves in a solvent to generate a homogenous mixture is referred to as a solute.
Calculation of volume of the solution 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 = 0.0200 M
Mass of NaCl = 38 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
= 38 g/ 58. 44 g/mol
= 0.650 mols.
Volume of NaCl solution can be calculated as:
Molarity = moles of solute / volume of solution in L.
0.0200 M = 0.650 moles/ Volume
Volume = 0.650 moles/ 0.0300 M
Volume = 21.66 L
Therefore, the volume of the solution will be 21.66 L.
