one of the substances in a new alkaline battery decomposes into 0.630 grams manganese and 0.370 grams of oxygen gas. what is the empirical formula of the substance

Respuesta :

The empirical formula of the substance is MnO₂.

The empirical formula is the most effective formula for a compound which is defined as the ratio of subscripts of the smallest viable whole wide variety of the factors gifted in the method. it is also referred to as the most effective components

The empirical formula of a chemical compound is the most effective complete wide variety ratio of atoms present in a compound. A simple instance of this idea is that the empirical method of sulfur monoxide, or SO, could genuinely be SO, as is the empirical formula of disulfur dioxide, S₂O₂

For Manganese:

Mn =  63.0/54.94 = 1.1467

For Oxygen:

O = 37/16 = 2.3125

Divide both by smaller value to get whole number mole ratios

Mn = 1.1467/1.1467

O = 2.3125/1.1467 = 2

Hence, the empirical formula of the compound is MnO₂
