Chapter 1, Problem 7MCP

(a)

Interpretation Introduction

Interpretation:

An aqueous solution is contained in a $\text{100}\text{.0}\text{mL}$ volumetric flask.  The temperature of the solution is $\text{20}{\text{.0}}^{\text{°}}\text{C}$.  The temperature of the solution in degree Fahrenheit has to be calculated.

(b)

Interpretation Introduction

Interpretation:

An aqueous solution is contained in a $\text{100}\text{.0}\text{mL}$ volumetric flask.  The temperature of the solution is $\text{20}{\text{.0}}^{\text{°}}\text{C}$.  The temperature of the solution in Kelvin scale has to be calculated.

(c)

Interpretation Introduction

Interpretation:

The change in the volume of the solution has to be given if the solution is warmed to $\text{25}{\text{.0}}^{\text{°}}\text{C}$.

Concept Introduction:

Density:

The ratio of mass and volume is said to be density.

  $\text{Density}\text{=}\frac{\text{mass}}{\text{volume}}$

(d)

Interpretation Introduction

Interpretation:

The change in the volume of the solution has to be given if the solution is cooled to $\text{15}{\text{.0}}^{\text{°}}\text{C}$.

Concept Introduction:

Refer to part (c).

(e)

Interpretation Introduction

Interpretation:

The proper use of volumetric flasks has to be explained from the information conveyed in part (c) and part (d).

(f)

Interpretation Introduction

Interpretation:

Density of the solution is an intensive property or an extensive property has to be given.

Concept Introduction:

Extensive property:

The property which depends on the amount of the matter is said to be an extensive property.  The change in the volume or mass of the matter changes the extensive properties.

Intensive property:

The property which does not depends on the amount of matter is said to be an intensive property.  The change in the volume or mass of the matter does not affect intensive properties.
