Measurement of Quantities

Procedure: To even scribble the lab, we (group) gathered the materials needed to do the experiment (list of materials higher up). To start the experiment, we took our closeness ingests and put them on the triple beam balance to let on the mass of the concentration consumes. and indeed we enter 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 succeeding(a) 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 then place the sample into the water and record the difference of the virgin number from the head start number of mL, and then recorded the measurement to the nearest 0.5 mL. We then metrical the minginess of the samples by using the aspect for density (Density is equal to the mass of a sample divided by its intensivenes s) 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 mensurable the diameter and height of the samples using the vernier caliper and save those values to the nearest .05 cm. We then metrical 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 fracture of both the aluminum and strappe r samples densities. For calculated the per! cent error of the densities we had to first find the actual densities of copper and aluminum. Then, we used this formula to find the percent error.If you want to detect a full essay, order it on our website: OrderCustomPaper.com
