How many fluorine atoms are present in 5.85 g of C₂F₄?

Key Concepts

Molar Mass

Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol). For C2F4, the molar mass is calculated by summing the atomic masses of its constituent elements: carbon (C) and fluorine (F). This value is essential for converting between grams and moles, which is necessary to determine the number of atoms in a given mass of the compound.

Avogadro's Number

Avogadro's number, approximately 6.022 x 10^23, is the number of particles (atoms, molecules, etc.) in one mole of a substance. This constant allows chemists to relate the macroscopic scale of substances (grams) to the microscopic scale (individual atoms or molecules). In this question, it will be used to find the number of fluorine atoms from the moles of C2F4.

Stoichiometry

Stoichiometry is the calculation of reactants and products in chemical reactions based on the conservation of mass. In this context, it involves determining the ratio of fluorine atoms to C2F4 molecules. Since each molecule of C2F4 contains four fluorine atoms, stoichiometry will help in calculating the total number of fluorine atoms present in the given mass of the compound.
