But we can prove that's correct by calculating the mass of each and adding them together. The SI unit for molar mass is kg/mol, though the decimal unit g/mol is more commonly used. The main conclusions drawn were that the best conversion percentage (100% of biodiesel) was reached when the methanol:oil molar ratio was 6:1, the reaction time was 75 min and the catalyst mass was 3% in relation to the oil mass used in this process. 17) What is the number of nitrogen molecules in 0.6 moles of N 2? The theoretical yield of water for this experiment is 15 grams. Conversions like this are possible for any substance, as long as the proper atomic mass, formula mass, or molar mass is known (or can be determined) and expressed in grams per mole. Thus, by knowing the molar mass, we can determine the number of moles contained in a given mass of a sample.
