Converting g cm^-3 into kg m^-3,

We know, 1 g = 10^-3 kg

1 cm = 10^-2 m

1 cm³ = 10^-6 m³

Therefore,

8.83 $\dfrac{\text {g}}{\text {cm}^3}$

= 8.83 $\dfrac{10^{-3}\text {kg}}{10^{-6} \text{m}^3}$

= 8.83 $\dfrac{10^{3}\text {kg}}{1 \text{m}^3}$

= 8.83 x 1000 kg m^-3

Hence,

8.83 g cm^-3 = 8830 kg m^-3
