Measurement of Quantities

Procedure: To even embark on the lab, we (group) gathered the materials needed to do the experiment (list of materials preceding(prenominal)). To start the experiment, we took our closeness ingests and put them on the doubled beam balance to let on the mass of the absorption consumes. and indeed we save the data we found to the nearest 0.001 gram. We also fipple flute the un surety for every measurement we took in the experiment. For our nigh pay back of measurements, we used a graduated cylinder to measure the people of the samples by using water displacement, which is where you start with a certain number of mL of water and and so place the sample into the water and record the difference of the untried number from the head start number of mL, and then recorded the measurement to the nearest 0.5 mL. We then metrical the tightness of the samples by using the aspect for density (Density is equal to the mass of a sample divided by its intensiveness ) then recorded it as g/mL. Then we started on Method B. Method B of the measurements prompted the group to find the volume of the samples using a vernier scale scale caliper.

This was not applicable to the foreign rock because of its dimensions. Continuing, we metrical the diameter and height of the samples using the vernier caliper and enter those values to the nearest .05 cm. We then calculate the volume of the samples by using the formula V=?r^2 h. The density we calculated again with the same formula as above and we then moved on to purpose the percent misconduct of both the aluminum and shit samples densities. For calculated the percent error of the densities we ha d to first find the actual densities of copp! er and aluminum. Then, we used this formula to find the percent error.If you want to trip up a full essay, order it on our website: OrderEssay.net
