# 35. For each of the following solutions, the mass of solute is given, followed by the total volume of the solution prepared. Calculate the molarity of each solution. a. 3.51 g NaCl: 25 mL c. 3.51 g NaCl: 75 mL b. 3.51 g NaCl; 50. mL d. 3.51 g NaCl; l.00 L

Interpretation Introduction

(a)

Interpretation:

The molarity of the given NaCl solution is to be calculated.

Concept Introduction:

The molarity of a solution is defined as the number of mole of solute dissolved in one liter of the solution. The formula for molarity is given as,

M=nV

Where,

• n represents the number of moles of the solute.
• V represents the volume of the solution.
Explanation

The mass of NaCl taken is 3.51g.

The volume of the NaCl solution is 25mL.

The molar mass of NaCl is 58.44gmol1.

The molarity of a solution is given as,

M=mMmV

Where,

• m represents the mass of the solute.
• V represents the volume of the solution.
• Mm represents the molar mass of the solute.

Substitute the value of m, V and Mm in the above equation
