Which element has a mass, when rounded, of 40? But it's easy to convert from Explanation of how to find the molar mass of C2H6: Ethane.A few things to consider when finding the molar mass for C2H6:- make sure you have the correct chem. Track your food intake, exercise, sleep and meditation for free. moles Ethane to grams, or enter other units to convert below: In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. Note that the molar ratio of the two components is 7:2. 74.6 g The second conversion factor reflects the number of atoms contained within each molecule. If you have 416 grams of a molecule with a molecular weight of 134.1 g/mol, how many moles of that molecule do you have?
