A manganese ore is composed of braunite and manganosite. We will solve for the mass of each component in the total ore by:
Manganese is a key component of extremely hard steel. The element occurs naturally in many oxides. A 542.3-g sample of a manganese oxide has an Mn/O ratio of 1.00/1.42 and consists of braunite (Mn2O3) and manganosite (MnO).
(a) How many grams of braunite and of manganosite are in the ore?
