Sample Calculation of Trial one with the 50ml graduated cylin
Trial 1:
Gross Mass: 60.35 Beaker Mass: 50.07
Difference between mass: total mass- Beaker Mass = difference between mass
60.2552.07
= (60.35g-52.07g)(0.01g+0.01g)
=10.18
10.18
Volume: 10.180.5ml=10.00.51% ml
Density = difference between Mass/Volume
= (10.18/10.0)
=1.0185.2%
=1.02 (g/ml)
Sample Calculation for Percentage Error:
The density of water is 1g/ml
Density= Mass/Volume
Actual Result: 0.842ñ0.006(g/ml)
The formula for calculating percentage error is (your result- accepted result)/accepted result.
(1-0.847)/1*100%=15.3%
