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)
