Aim: To measure the stack of some(prenominal) different volumes of peeing and meth and use these to calculate their densities. Equipment:?electronic balance?Water? rubbish hydrochloride stoppages?Measuring piston sleeping accommodation?100mL beakerRisk Assessment:HazardControlUse of glass instruments ? sustenance little employ may lead to breakageCarePart A: The dumbness of water supply supplyMethod:1)The tummy of the quash bar piston chamber was enter use the electronic balance. 2)Water was added to the mensuration piston chamber using the 100mL beaker. 3)The have big money of the measuring cylinder and water was recorded. 4)The mass of the water and the volume of the water was metric using the difference surrounded by the above apprizes (Combined mass of water and measuring cylinder ? mass of measuring cylinder). 5)This subprogram was repeated another 4 (reliability). Results: running play 1Trial 2Trial 3Trial 4Trial 5Mass of 100mL measuring cylinder (g)134134134134134Mass of water + cylinder (g)154164174184194Mass of water (g)2030405060Volume of water (ml)2030405060Average Density metric as 1 g/mL. severalise results: assembly numberDensity calculated112131415161Questions:1)How did your tax analyse with those of the rest of the class?The value was consistent throughout the class. 2)Suggest workable reasons for variations between groups. There was no variation ? as seen in the above table. ***************************************************Part B: The Density of folderolMethod:1)The mass of an sparkler engine block was measured using the electronic balance. 2)The screwball cube was submerged in a measuring cylinder modify with water up to the 40mL line.
3)The list of water that was displaced by the water icing the puck cube was recorded (this is stir to the volume of the ice cube in milliliters). 4)The results were recorded and the mapping was repeated 5 times to increase reliability. Results:Trial 1Trial 2Trial 3Trial 4Trial 5Mass of Ice (g)713142120Volume of Ice (mL)814152220Density (g/mL)0.880.930.930.951The number parsimony was calculated as 0.938 g/mL (3 dp).
