Tool Overview: Molar Mass of Cyclohexane (C6H12) Solving for the atomic mass of Cyclohexane (C6H12) Need to know the atomic mass of a Cyclohexane molecule? So, plugging these values in the formula above, we get: mass = 778.5 1 1 10-6 0.001 mass = .00077850.001 mass = 0.7785 gram (answer) Thermal data. It may be easier to put the test tube in a beaker to take the mass. Your institution may already be a subscriber. We use the most common isotopes. Weigh the first empty tube, stir bar included, to 0.01 g (pan balance). 0000002873 00000 n
