Weight of stone in air=245N

Mass of stone =$\frac{245}{9.81}$=24.97Kg

Volume=$\frac{mass}{(density \ of \ water)}$=$\frac{24.97}{1000}=.02497 m^3$ ….(ans)

$ρ_{fluid}$=s×1000

Mass of stone in water= $\frac{168}{9.81}=17.25kg$

$ρ_{fluid}$=$\frac{mass}{volume}=\frac{17.25}{.02497}$=685.823

Specific gravity=$ρ_{fluid}{1000}$=$\frac{685.823}{1000}$=.6858 ……..(ans)
