Chapter 8, Problem 8.78P
Interpretation Introduction

(a)

Interpretation:

The number of moles of solute present in 250 mL of 0.55 MNaNO3 is to be calculated.

Concept introduction:

Several concentration units may be used to express the concentration. It is often useful to express the concentration in terms of percentage. This can be expressed as the amount of solute in grams dissolved in 100 mL of solution that is termed as weight by volume percentage. This is useful to express the concentration of solid solutes. The other way is to express the number of milliliters of solute per 100 mL of the solution. This is called the volume /volume percentage which is useful to express the concentrations of liquid solutes.

The formula to calculate molarity is given as follows:

  Molarity(mol/L)=number of molesvolume(L)

Interpretation Introduction

(b)

Interpretation:

The number of moles of HNO3 present in 145 mL of 4 M

  HNO3 is to be calculated.
