For example, for hydrogen, the relative atomic mass is 1.007; for carbon, it is 12.0107; for oxygen, it is 15.9994; and for chlorine, it is 35.453. Manage Settings You can see that in Na2O, there are 2 Sodium atoms and 1 Oxygen atom. Uranium hexafluoride | UF6 - PubChem Apologies, we are having some trouble retrieving data from our servers. a) CH4 b) CO2 c) UF6 molar mass of CH4 = 16 g molar mass of CO2 = 44 g molar mass of UF6 = 352 g 1 mole CH4 1 mole CO2 1 mole UF6 Density of CH4 = (16 g ) 1 mole CH4 x ( 1 mole CH4) = 0.71384 g/L 22.414 L molar mass of CO2 = (44 g) x (1 mole CO2) 1 mole CO2 22.414L molar mass of UF6 = (352 g) 1 mole UF6 14. x ( 1 mole UF6) 22.414 L = 1.9631 g/L = I hope you have understood the short and simple calculation for finding the molar mass of Uranium hexafluoride. Typically, gaseous molecules have a speed of hundreds of meters per second (hundreds of miles per hour). This site explains how to find molar mass.
