Question

The volume of $50g$ a substance is $20c{m}^3$. Find its density. If the density of water is$1\raisebox{1ex}{$g$}\!\left/ \!\raisebox{-1ex}{$c{m}^3$}\right.$, will the substance float or sink.

Answer 1

$$\begin{gathered} Step1:- \\ Givendata:-mass=50g \\ volume=20c{m}^3 \\ densityofwater\left({\rho }_{water}\right)=1\raisebox{1ex}{$g$}\!\left/ \!\raisebox{-1ex}{$c{m}^3$}\right. \\ Step2:- \\ Formula\Rightarrow Density=\frac{mass}{volume} \\ Step3:-Tofind:-densityofasubsatnce \\ Solution,Density=\frac{mass}{volume} \\ density=\frac{50}{20} \\ density=2.5\raisebox{1ex}{$g$}\!\left/ \!\raisebox{-1ex}{$c{m}^3$}\right. \\ Step4:-densityofsubs\tan ce>densityofwater \\ \Rightarrow 2.5\raisebox{1ex}{$g$}\!\left/ \!\raisebox{-1ex}{$m^3$}\right.>1\raisebox{1ex}{$g$}\!\left/ \!\raisebox{-1ex}{$m^3$}\right. \\ Step5:-1.Asthedensityofthesubs\tan ceisgreaterthanwater. \\ 2.Objectwill\sin kinwater. \end{gathered}$$
