If you have 0.00812 mol of H2CO3, how many molecules Of course many on here do, so its not really definitive, its just a birds of a feather kind of relation. When added, the atoms in KMnO4 yield an overall neutral charge, as specified by the formula. The molar mass of KMnO 4 is 158.034 g mol - 1. Based on the size of the atoms, do you expect the atomic masses of elements (a) and (c) to be greater than or less than (b)? The reason is that the molar mass of the substance affects the conversion. Molecular weight of KMnO4=158.034 g/mol 2.50 X 158.034=395.085 Since molecular weight of Oxygen=15.9994g/mol, therefore, 395.085/15.9994=24.694 moles of Oxygen. Athletes foot and impetigo.
