Answer 2

Calculating the Mass of a Single Oxygen Molecule in Grams

To calculate the mass of a single oxygen molecule in grams, we can use the following approach:

Step 1: Determine the Molar Mass of Oxygen The molar mass of oxygen (O2) is approximately 32.00 grams per mole.

Step 2: Convert Molar Mass to Mass of a Single Molecule To find the mass of a single oxygen molecule, we can use Avogadro's number, which is approximately 6.022 x 10^23 molecules per mole. By dividing the molar mass by Avogadro's number, we can calculate the mass of a single oxygen molecule in grams.

Step 3: Calculation Using the molar mass of oxygen (32.00 g/mol) and Avogadro's number (6.022 x 10^23 molecules/mol), we can calculate the mass of a single oxygen molecule as follows:

Mass of a single oxygen molecule = Molar mass of oxygen / Avogadro's number
                                = 32.00 g/mol / 6.022 x 10^23 molecules/mol
                                ≈ 5.31 x 10^-26 grams

Therefore, the mass of a single oxygen molecule is approximately 5.31 x 10^-26 grams.

This calculation is based on the molar mass of oxygen and Avogadro's number, which are fundamental concepts in chemistry.
