Answer 1

Answer:

Error percentage = 1.326% , 1.35% ,  5.37%

density = mass / volume

For first sample:

density = 37.22/11.5 = 3.2365 g/ml

then percentage error = 100% -  (3.2365/3.28 ) * 100 = 1.326%

For second sample:

density = 37.21/11.5 = 3.2356 g/ml

then percentage error = 100% - ( 3.2356 / 3.28 ) *100 = 1.35%

For third sample:

density = 37.25/12 = 3.104 g/ml

then percentage error = 100% - ( 3.104 / 3.28 ) *100 = 5.37%
