The mineral manganosite is a compound of ⁵⁵Mn and ¹⁶O. If 77% of the mass of manganosite is due to manganese, what is the empirical formula of manganosite

Question

Quizplus · Accepted Answer

The empirical formula of manganosite is MnO. This is determined by the given mass percentage of manganese (77%) and the fact that the only other element present is oxygen. Given the atomic masses of manganese (approximately 55 g/mol) and oxygen (approximately 16 g/mol), the ratio of their masses in the compound aligns with the simplest ratio of 1:1, leading to the empirical formula MnO.
