Determining Molar Ratios. The molar ratios identify how many moles of product are formed from a certain amount of reactant, as well as the number of moles of a reactant needed to completely react with a certain amount of another reactant. For example, look at this equation: $CH_{4} + 2O_{2} \rightarrow CO_{2} + 2H_{2}O$

Structure, properties, spectra, suppliers and links for: BTPPC, 1100-88-5. K2CO3 is the chemical formula for potassium trioxocarbonate For molar mass of K2CO3, use the molar masses: Potassium, K = 39g; Carbon, C = 12g; Oxygen, O = 16g K2CO3 = [ (39g x 2) + 12g + (16g x 3) ] = 78g + 12g + 48g = 138g/mol Thus, the molar mass of K2CO3 is 138g/mol
