Chapter 3, Problem 3.97P

Interpretation Introduction

Interpretation:

The mass(g) of carbon tetrafluoride formed by the reaction of $60\text{ g}$ each of cyanogen and fluorine gas is to be calculated.

Concept introduction:

In a balanced chemical equation, the total mass of reactants and products are equal in a balanced chemical equation, thus, it obeyed the law of conservation of mass. Also, the amounts of substances in a balanced chemical reaction are stoichiometrically equivalent to each other.

A limiting reagent is the one that is completely consumed in a chemical reaction. The amount of product formed in any chemical reaction has to be in accordance with the limiting reagent of the reaction.

The formula to calculate moles is as follows:

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

The expression to calculate the mass from the moles of a substance is as follows:

$\text{Mass}\left(\text{g}\right)=\left(\text{Amount}\left(\text{mol}\right)\right)\left(\text{Molar mass}\left(\text{g/mol}\right)\right)$ (2)
