Chapter 3, Problem 3.95P

(a)

Interpretation Introduction

Interpretation:

The mass of oxygen needed to burn $5.50\text{ mL}$ of butane is to be calculated.

Concept introduction:

The formula to calculate moles is as follows:

  $\text{Amount}\left(\text{mol}\right)=\frac{\text{mass}}{\text{molecular mass}}$        (1)

The formula to calculate density is as follows:

  $\text{density}=\frac{\text{mass}}{\text{volume}}$        (2)

(b)

Interpretation Introduction

Interpretation:

The amount(mol) of ${\text{H}}_2\text{O}$ formed on burning of $5.50\text{ mL}$ of butane is to be calculated.

Concept introduction:

The formula to calculate moles is as follows:
