Solutions

Chapter 8, Problem 92AP
Interpretation Introduction

(a)

Interpretation:

The mass of carbon in grams, the percent carbon by mass, and the number of individual carbon atoms present in 7.819 g of carbon suboxide, CO32 should be determined.

Concept Introduction:

Number of moles is equal to the ratio of given mass to the molar mass.

The mathematical expression is given by:

Number of moles = Given massMolar mass

Molar mass of the molecule is equal to the sum of the masses of atoms present in the molecule.

Interpretation Introduction

(b)

Interpretation:

The mass of carbon in grams, the percent carbon by mass, and the number of individual carbon atoms present in 1.53×1021 molecules of carbon monoxide should be determined.

Concept Introduction:

Number of moles is equal to the ratio of given mass to the molar mass.

The mathematical expression is given by:

Number of moles = Given massMolar mass

Molar mass of the molecule is equal to the sum of the masses of atoms present in the molecule.

Interpretation Introduction
