To do this you will determine the composition by mass of magnesium oxide calculate the percent composition and compare your results with other groups working on the same experiment. Put on safety goggles and lab apron.
DETERMINATION OF THE COMPOSITION OF A MIXTURE —– LEARNING GOALS 1. Note that best results will be obtained when each aliquot taken for analysis is representative of the sample. Make sure that your equipment is very clean so that you will get the best possible results. An alloy is a mixture of two or more elements one of them being a metal and steel is an alloy of iron containing small amounts of. Percent Composition of Hydrates continued Procedure 1. The analysis of alcohol content in this experiment utilizes the density relationship which relates the quantity of matter to the volume it occupies.
