m I. Title: Density lab 1 II. Purpose The purpose of lab one was to find the density of a foreign object and to find what that object would be with that density.

III. Data Length (cm) Height (cm) Width (cm) Mass (g) 1. .89 .86 .99 1.436 2. .98 .89 .91 7.475 3. 1.32 1.29 1.25 15.749 IV. Calculations Volume(cm3) Density (g/cm3) 1. .757796 1.9 2. .793702 9.4 3. 2.1285 7.40 EX1. EX2.

L*W*H=Volume Mass/Volume=Density .89*.86*.99=.757796 1.436 = 1.894969095 Sig. Fig.= 1.9 .757796 EX3.

|Actal-experimental|*100=perent error actual |1.9 - 2.26 | *100 = 15.92920354 = 16% 2.26 V. Conclusions We identified three objects by figuring out their density and comparned it to a list of elements given on the bored.

Graphite Copper Steel Experimental density 1.9 9.4 7.4 Actual Density 2.26 8.96 7.23 VI. Error Analysis The reasons for the errors could be the shape of the block.

they have been handled many of times and could have wore down. this would affect the volume of the object. Also when calculating the mass the scale would stick from time to time and we could have calculated off by a bit. we also didn't have a scale that would messier very far.
