Task 2: Density and its Uncertainty To find the density of aluminum, a student used an aluminum cube. She found that its mass is 58.3 i 0.13 and its volume is 21.20 i 0.07cm3. Recall that the density of an object is given by p=M/V, where M is the mass and V is the volume. [a] Find the aluminum density and its uncertainty. Use Eq. [1-7] to find the uncertainty. (b) If the accepted value for aluminum density is 2.71g/cm3. find the percent error in the measured value. Clearly show all steps of your work on paper then take a picture of your calculations and paste it into the spreadsheet that you used for Task]
