Answer 2

Calculating the Relative Molecular Mass of P2O3

To calculate the relative molecular mass of P2O3, we need to consider the atomic masses of the elements involved and then sum them up according to the molecular formula.

The relative molecular mass of a compound is calculated by adding up the atomic masses of all the atoms in a molecule.

The atomic masses of the elements involved are as follows: - Phosphorus (P) has an atomic mass of approximately 30.97 u. - Oxygen (O) has an atomic mass of approximately 16.00 u.

Now, let's calculate the relative molecular mass of P2O3.

The molecular formula for phosphorus trioxide (P2O3) indicates that there are 2 phosphorus atoms and 3 oxygen atoms in each molecule.

Using the atomic masses provided, we can calculate the relative molecular mass of P2O3 as follows:

Relative Molecular Mass of P2O3: = (2 * Atomic mass of P) + (3 * Atomic mass of O) = (2 * 30.97 u) + (3 * 16.00 u) = 61.94 u + 48.00 u = 109.94 u

Therefore, the relative molecular mass of P2O3 is approximately 109.94 u.
