Homework Statement
The density of a cylinder is calculated from the following data:
mass m= (9.1±1.1)g , diameter d = (2.8±0.2) cm , and height H= (4.1±0.6) cm.
The error on the density, before rounding, is ( in g /cm3 )
The formula for calculating error on density is: error = (absolute error in mass / mass) + (absolute error in volume / volume)
To determine the absolute error in mass, subtract the measured mass from the accepted or true mass. To determine the absolute error in volume, subtract the measured volume from the accepted or true volume.
Yes, you can use percentage error to calculate error on density by multiplying the calculated error by 100%.
Calculating error on density helps to determine the accuracy of your measurements and the precision of your equipment. It also allows for comparisons between different experiments or measurements.
To reduce error on density calculations, it is important to use precise and accurate measuring equipment, repeat measurements multiple times, and take care to minimize any sources of error, such as air bubbles in the sample or parallax errors in reading instruments.
