# 33. For each of the following solutions, the number of moles of solute is given, followed by the total volume of the solution prepared. Calculate the molarity of each solution. a. 0.521 mol NaCl; 125 mL b. 0.521 mol NaCl; 250. mL c. 0.521 mol NaCl; 500. mL d. 0.521 molNaCl; 1.00 L

Interpretation Introduction

(a)

Interpretation:

The molarity of the given solution is to be calculated.

Concept Introduction:

The division of total number of moles of solute with the volume of the solution in liters is termed as molarity. The unit of molarity is mol/L or M. The formula used to express the molarity of the solution is,

Molarity=MolesofsoluteVolumeL.

Explanation

The given moles of NaCl is 0.521mol.

The given volume of NaCl solution is 125mL.

The conversion of mL into L is done as,

1mL=1×103L

Thus, the volume of NaCl solution becomes,

125mL=0.125L

The molarity of the solution is calculated by the formula,

Molarity=Moles

Interpretation Introduction

(b)

Interpretation:

The molarity of the given solution is to be calculated.

Concept Introduction:

The division of total number of moles of solute with the volume of the solution in liters is termed as molarity. The unit of molarity is mol/L or M. The formula used to express the molarity of the solution is,

Molarity=MolesofsoluteVolumeL.

Interpretation Introduction

(c)

Interpretation:

The molarity of the given solution is to be calculated.

Concept Introduction:

The division of total number of moles of solute with the volume of the solution in liters is termed as molarity. The unit of molarity is mol/L or M. The formula used to express the molarity of the solution is,

Molarity=MolesofsoluteVolumeL.

Interpretation Introduction

(d)

Interpretation:

The molarity of the given solution is to be calculated.

Concept Introduction:

The division of total number of moles of solute with the volume of the solution in liters is termed as molarity. The unit of molarity is mol/L or M. The formula used to express the molarity of the solution is,

Molarity=MolesofsoluteVolumeL.
