Question
Can someone please answer it ASAPDescribe how a metal sample should be placed into a graduated cylinder when determining the density?
In this lab activity you were learning about how to minimize error when using common lab equipment. In the space below list 2 possible sources of error and what you could do to minimize them. Assume that all of your math is done correctly, so you only have to consider techniques.

Explanation / Answer
Density is given by,
Density= Mass/Volume.
Here mass can be measured by weighing the Given sample of metal.
Tu determine the volume of metal (in cm³) we take a graduated cylinder and then dip the metal sample in a given volume of water in the graduated cylinder. The volume of liquid displaced in the graduated cylinder will be the volume of metal sample (in cm³) .
By dividing the Mass (in Kg) to the volume (in cm³) we get the density in Kg/cm³.
.
Sources of Error : 1) as the volume of the liquid depends upon the temperature so to minimise the error we have to use the corrected volume of liquid at that particular temperature.
2) As density of liquid depends upon temperature so to minimise any Error due to temperature changes perform the experiment at the same temperature.
3) the third possibility of Error is in the volume measurement. To minimise error of this kind take accurate graduated cylinder.
