Moles. Compounds. To find the mass of one mole of a compound, just add up all the RAMs of the elements of the compound, taking account of the formula. The number you get is called the Relative Formula Mass. It is the mass of one mole of the compound in grams. The Relative Formula Mass can be written as M r or RFM. For example, the mass of one mole of carbon dioxide (CO 2) is

Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium.At standard temperature and pressure,
Oct 06, 2011 · The key difference between carbonate and bicarbonate is that the carbonate ion has -2 electrical charge whereas, the bicarbonate has -1 electrical charge. The human body produces carbon dioxide as a by-product of metabolism.Most of this carbon dioxide dissolves in blood plasma and present in the form of bicarbonate. Carbonate and bicarbonate system is mainly responsible for.

1. Introduction. Microbially-induced calcium carbonate precipitation (MICP) is a biomineralisation process, where speciﬁc microorganisms induce the precipitation of calcium carbonate (CaCO 3).These biological reactions are usually facilitated by either the enzymatic hydrolysis of urea  or the interconversion of CO 2 to HCO 3 − by the enzyme, carbonic anhydrase .
