Chapter 3: Problem 79

Many elements exist as polyatomic molecules. Use atomic masses to calculate the molecular masses of the following: \begin{equation} \begin{array}{l}{\text { a. } \mathrm{O}_{2}} \\ {\text { b. } \mathrm{P}_{4}} \\ {\text { c. } \mathrm{S}_{8}}\end{array} \end{equation}

Short Answer

Expert verified

The molecular masses of \(\mathrm{O}_{2}\), \(\mathrm{P}_{4}\), and \(\mathrm{S}_{8}\) are 32.00 amu, 123.88 amu, and 256.48 amu, respectively.

Step by step solution

Calculate the Molecular Mass of O2

To calculate the molecular mass of \(\mathrm{O}_{2}\), multiply the atomic mass of Oxygen (16.00 amu) by the number of atoms in the molecule (2) to obtain \(16.00 \times 2 = 32.00 \) amu

Calculate the Molecular Mass of P4

Similarly, to calculate the molecular mass of \(\mathrm{P}_{4}\), multiply the atomic mass of Phosphorus (30.97 amu) by the number of atoms in the molecule (4) to obtain \(30.97 \times 4 = 123.88 \) amu

Calculate the Molecular Mass of S8

Finally, to calculate the molecular mass of \(\mathrm{S}_{8}\), multiply the atomic mass of Sulfur (32.06 amu) by the number of atoms in the molecule (8) to obtain \(32.06 \times 8 = 256.48 \) amu
