Ans. Mass of body = 22.42 g
Volume of body = 4.7 cc
Density = {tex}{mass\over volume } = {22.42\over 4.7}{/tex} = 4.77021 g/cm3
Error in measurement of mass = 0.01 g
So Mass = 22.42 - 0.01 = 22.41 g
Error in measurement of Volume = 0.1 cc
So Volume = 4.7 - 0.1 = 4.6 cc
Now Density = {tex}{mass\over volume } = {22.41\over 4.6}{/tex} = 4.87174 g/cm3
Error in Density = 4.87174 - 4.77021 = 0.10153 g/cm3
%/ error = {tex}{0.10153\over 4.77021}\times 100{/tex}
= {tex}0.02128 \times 100 = 2.128 \% = 2.1\%{/tex}
