9) Report the value of the volume you obtained for your cylinder in “proper form:”
D = 19.27 ± 0.04
H = 28.40 ± 0.01
V= ¼ X pie(19.27∧2)(28.40) = 8282.694646
Vmax = V= ¼ X pie(19.31∧2)(28.41) = 8320.044759
Vmax – V = 37.3501131 (uncertainty)
Round V to 1 significant figure = 4 X 10∧1mm3
Round volume to same power 10 = 828.2 X 10∧1mm3
Volume = (8.28 ± 0.01)x 4 mm3
10) Report the value of the density you obtained for your cylinder in “proper form:”
p = m / v
density = 2.70g/cm 3
( 8.28 ± 0.01)x 4 mm3 ) / (2.70g/cm^3) =
=(3.1 ± 0.5) g/cm3
