50. Calculate the number of moles of each ion present in each of the following solutions.

a. 10.2 mL of 0.451 M AlCl3 solution

b. 5.51 L of 0.103 M Na3PO4 solution

c. 1.75 mL of 1.25 M CuCl2 solution

d. 25.2 mL of 0.00157 M Ca(OH)2 solution

Interpretation Introduction

(a)

Interpretation:

The number of moles of each ion in 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=NumberofmolesofsoluteVolumeofsolutioninLiters.

Explanation

It is given that 10.2mL of 0.451M

AlCl3 solution is prepared.

The conversion of units of volume into L is done as,

10.2mL=10.21000L=0.0102L

The number of moles of a solute is calculated by the formula,

Numberofmolesofsolute=Volumeofsolution×Molarity

Substitute the values of volume of solution and molarity of AlCl3 solution in the above expression.

Numberofmolesofsolute=0.0102L×0.451M=0.0046moles

The compound AlCl3 has one mole of Al3+ ions and three moles of Cl ions
