Chapter 5, Problem 5.86P

Interpretation Introduction

(a)

Interpretation:

The mass of vitamin D present in 3.6 mol of vitamin D is to be determined.

Concept Introduction:

The formula that will be used −

  $numberofmoles=\frac{mass}{Molarmass}$

Or,

  $mass=numberofmoles\times Molarmass$

Interpretation Introduction

(b)

Interpretation:

The mass of the vitamin D present in 0.58 mol of vitamin D is to be determined.

Concept Introduction:

The formula that will be used −

  $numberofmoles=\frac{mass}{Molarmass}$

Or,

  $mass=numberofmoles\times Molarmass$

Interpretation Introduction

(c)

Interpretation:

The mass of vitamin D for $7.3\times {10}^{24}molecules$ of vitamin D is to be determined.

Concept Introduction:

The formula that will be used −

  $numberofmoles=\frac{mass}{Molarmass}$

Or,

  $mass=numberofmoles\times Molarmass$

Interpretation Introduction

(d)

Interpretation:

The mass of vitamin D for $6.56\times {10}^{22}molecules$ of vitamin D is to be determined.

Concept Introduction:

The formula that will be used −

  $numberofmoles=\frac{mass}{Molarmass}$

Or,

  $mass=numberofmoles\times Molarmass$
