Determination of the relative atomic mass of Lithium Implementing For all my results I have decided to use three significant figures. This is because the apparatus I was told to use for the experiment gave me results to three significant figures. There was, therefor, no point in calculate to any further accuracy as this would just define a figure that has already been calculated to a specific depth of accuracy. Results Method 1 Mass of Lithium used 1.09 g Volume of gas produced 175 cm3 Method 2 1 2 3...
to improve the experimental procedure for this and so they are inaccuracies that I cannot change. The third inaccuracy is the fact the gas expanded when it came from the Li and water as it was hot so the final gas reading would be greater than it should be and so it effected my results.

I would of used a percentage error type of evaluation but as I don?é?í?é?ªt have specific measurements that could of shown me how inaccurate the data I collected was I cannot use percentage errors for some data?é?í?é?ªs and not for others.
