The density is $= {8.510}^{2} k g m^{- 3}$ $=8.510^2kgm^-3$

Explanation:

The mass is $m = 25 g = 0.025 k g$ $m=25g=0.025kg$

The volume is $v = 29.4 c m^{3} = 29.4 \cdot 10^{- 6} m^{3}$ $v=29.4cm^3=29.4*10^-6m^3$

The density is

$ρ = \frac{m}{v} = \frac{0.025}{29.4 \cdot 10^{- 6}} = \frac{2.5 \cdot 10^{- 2}}{29.4 \cdot 10^{- 6}}$ $rho=m/v=0.025/(29.4*10^-6)=(2.5*10^-2)/(29.4*10^-6)$

$= 0.085 \cdot 10^{4}$ $=0.085*10^4$

$= {8.510}^{2} k g m^{- 3}$ $=8.510^2kgm^-3$
