Dinitrogen pentoxide is a chemical compound composed of nitrogen and oxygen. Its chemical formula is N₂O₅.
To calculate the molecular mass of dinitrogen pentoxide, we need to add up the atomic masses of all the atoms in the formula. The atomic masses are approximately:
- Nitrogen (N): 14.01 g/mol
- Oxygen (O): 16.00 g/mol
In N₂O₅, there are 2 nitrogen atoms and 5 oxygen atoms. Therefore, we can calculate the total molecular mass as follows:
- Molar mass of nitrogen: 2 x 14.01 g/mol = 28.02 g/mol
- Molar mass of oxygen: 5 x 16.00 g/mol = 80.00 g/mol
Adding these together gives:
28.02 g/mol (from Nitrogen) + 80.00 g/mol (from Oxygen) = 108.02 g/mol
So, the molecular mass of dinitrogen pentoxide (N₂O₅) is 108.02 g/mol.
