What is the molecular weight of dipotassium oxide?

The molecular formula of dipotassium oxide is K₂O. To calculate its molecular weight, you sum the atomic weights of its constituent elements: potassium (K) has an atomic weight of approximately 39.1 g/mol, and oxygen (O) has an atomic weight of about 16.0 g/mol. Therefore, the molecular weight of K₂O is (2 × 39.1) + (1 × 16.0) = 94.2 g/mol.
