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.
By looking up the molar masses of the elements of the product and adding them together, you can determine the molar mass of the product. For example, the molar mass for Na is 22.99 g. The molar mass for Cl is 35.45. In NaCl2, there are 2 moles of Cl, so multiply 35.45 by 2.a + Cl2, which gives you NaCl2. Determine the mass of the product. When the experiment is completed, the mass is typically calculated by weighing the product with a gram balance. For example, the final mass of the product may be 202.0 grams of sodium chloride (NaCl2). Determine the molar mass of the product.
