Chapter 13, Problem 13.166P

(a)

Interpretation Introduction

Interpretation:

The moles of carbon dioxide is to be calculated.

Concept introduction:

Henry’s law gives the quantitative relationship between the pressure of the gas and its solubility. It states that the amount of gas dissolved in a liquid is proportional to the partial pressure of the gas. Higher the partial pressure of the gas, more will be its solubility and vice-versa.

The formula to calculate the solubility of gases according to Henry’s law is as follows:

$S_{\text{gas}}=k_{\text{H}}\times P_{\text{gas}}$ (1)

Here, $S_{\text{gas}}$ is the solubility of the gas.

$k_{\text{H}}$ is Henry’s constant.

$P_{\text{gas}}$ is the partial pressure of the gas.

Interpretation Introduction

Interpretation:

The moles of carbon dioxide after the soda has gone flat is to be calculated.

$P_{\text{gas}}$ is the partial pressure of the gas.

(c)

Interpretation Introduction

Interpretation:

The volume of carbon dioxide is to be calculated.

Concept introduction:

The formula of an ideal gas equation is as follows:

$PV=nRT$ (2)

Here, $P$ is the pressure of the gas.

$V$ is the volume of gas.

$n$ is the number of moles of gas.

$R$ is the universal gas constant.

$T$ is the absolute temperature of the gas.

The conversion factor to convert $°\text{C}$ to ${}^{°}\text{K}$ is as follows:

$T\left({}^{°}\text{K}\right)=T\left({}^{°}\text{C}\right)+273.15\text{K}$
