When re-attaching the shifter to the linkage with the long bolt, there may be some difficulty getting the base of the shifter, with the new bushings, seated between the arms of the linkage. To make this part easier, I inserted a pair of pliers between those arms and stretched them out a bit.
I also taught Masters Students at Imperial for 3 years. The molecular formula for cyclohexane is C6H12, therefore one molecule of cyclohexane contains 6 carbon atoms and 12 hydrogen atoms. The relative atomic mass (RAM) of carbon is 12.011 g/mol. For hydrogen the RAM is 1.008 g/mol. Cyclohexane's molar mass is thus: (6 x 12.011) + (12 x 1.008) = 84.162 g/mol.
Step 4: Find the mass percent composition of each element. To find the mass percent composition of an element, divide the mass contribution of the element by the total molecular mass. This number must then be multiplied by 100% to be expressed as a percent.Mass percent composition of K = mass contribution of K/molecular mass of K 3 Fe(CN) 6 x 100%.ach element's contribution is expressed as a percentage of the whole. This step by step tutorial will show the method to determine the mass percent composition of a molecule. Example: Calculate the mass percent composition of each element in a potassium ferricyanide, K 3 Fe(CN) 6 molecule.
