The molar mass of dinitrogen monoxide (N2O) is calculated by summing the atomic masses of all the atoms in the molecule. Dinitrogen monoxide consists of two nitrogen atoms and one oxygen atom.
The atomic mass of nitrogen (N) is approximately 14.01 g/mol, and for oxygen (O), it is about 16.00 g/mol. Therefore, the calculation for the molar mass of N2O is as follows:
Molar Mass = (2 x Atomic Mass of N) + (1 x Atomic Mass of O)
Molar Mass = (2 x 14.01 g/mol) + (1 x 16.00 g/mol)
Molar Mass = 28.02 g/mol + 16.00 g/mol = 44.02 g/mol
Thus, the molar mass of dinitrogen monoxide is 44.02 g/mol.
