For each of the following solutions, the mass of the solute is given, followed by the total volume of solution prepared. Calculate the molarity.

a. 5.0 g of BaCl2; 2.5 L

b. 3.5g of Kl3r:75mL

c. 21.5 g of Na2CO3; l75mL

d. 55 g of CaCl2; 1.2 L

Interpretation Introduction

(a)

Interpretation:

The molarity of the given solution is to be calculated.

Concept Introduction:

The atomic mass of an element is defined as the sum of number of protons and number of neutrons. Molar mass of an element is determined from atomic mass of an element.

The number of moles is calculated by the formula,

Moles=MassgMolarmass

The molarity is calculated by the formula,

Molarity=NumberofmolesofsoluteVolumeofsolutionL.

Explanation

The mass of BaCl2 and volume of the solution is given to be 5.0g and 2.5L respectively.

The molar mass of BaCl2 is 208.23g/mol.

The number of moles is calculated by the formula,

Moles=MassgMolarmass        (1)

Substitute the values of mass and molar mass of BaCl2 in the equation (1).

Moles=5.0g208.23g/mol=0

Interpretation Introduction

(b)

Interpretation:

Concept Introduction:

The atomic mass of an element is defined as the sum of number of protons and number of neutrons. Molar mass of an element is determined from atomic mass of an element.

The number of moles is calculated by the formula,

Moles=MassgMolarmass

The molarity is calculated by the formula,

Molarity=NumberofmolesofsoluteLitersofsolution.

Interpretation Introduction

(c)
