Answer:

The molarity of the NaCl solution is 1.66 M.

Explanation:

Molarity is the unit of concentration of a solution. It is defined as the number of moles of solute per liters of solution. In variable expression, molarity is

M =

To solve the problem, we are going to use the definition of molarity.

Given:

• 650 mL solution
• 63 grams of NaCl

Required:

Solution:

Solve first the number of moles of NaCl from 63 grams. To do this, we will use the molar mass of NaCl which is 58.44 g/mol.

• 63 grams NaCl ×
  = 1.078029 mol NaCl
• M =
• M =
• M = 1.66 molar

Note that we convert the given volume of the solution from mL to L because the definition of molarity needs the volume of solution in terms of liters.

Therefore, the molarity of the NaCl solution is 1.66 M.
