Question

The following are the observations recorded by Naresh while performing the experiment to
determine the density of a solid (denser than water) by using a spring balance and a

measuring cylinder.


Observations:

Zero error in the spring balance, x = +2g.wt

Observed weight of the solid in air, m1 = 42g.wt

Initial reading of the water level in the measuring cylinder, v1 = 32 cc

Final reading of water level in the measuring cylinder after

immersing the solid in water, v2 = 40 cc

Perform the following calculations on the basis of the above given data.

Calculations:


Corrected weight of the solid in air, m = ______________________g.wt

Mass of the solid, M = ________________________g

Volume of the solid =________________________cc

Density of the given solid = ______________________g/cc...
