Chapter 12, Problem 49PE

(a)

Interpretation Introduction

Interpretation:

Volume of ${\text{CO}}_2$ produced if $6.24{\text{ g CaCO}}_3$ is decomposed at STP has to be determined.

Concept Introduction:

Ideal gas law represented as equation to relate its volume and pressure with its temperature. Expression for ideal gas equation is as follows:

  $PV=nRT$        (1)

Here,

$P$ is pressure of the gas.

$V$ is volume of gas.

$n$ denotes moles of gas.

$R$ is gas constant.

$T$ is temperature of gas.

(b)

Interpretation Introduction

Interpretation:

Number of moles of ${\text{CaCO}}_3$ required to produce $52.\text{6 L}$ of ${\text{CO}}_3$ at STP has to be determined.
