# 44. How many moles of the Indicated solute does each of the following solutions contain? a. 1 2.5 mL of 0. 104 M HCI b. 27.3 mL of 0.223 M NaOH c. 36.8 mL of 0.501 M HNO3 d. 47.5 mL of 0.749 M KOH

Interpretation Introduction

(a)

Interpretation:

The moles of the indicated solute in the given solution are 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=NumberofmolesofsoluteLitersofsolution.

Explanation

The volume and molarity of HCl solution is given to be 12.5mL and 0.104M respectively.

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

12.5mL=12.51000L=0.0125L

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 HCl solution in the above expression
