What is the density of water in $\mathrm{kg} \mathrm{dm}^{-3}$ if it's density in $\mathrm{g} \mathrm{cm}^{-3}$ is 0.863 ?
  1. $4.60$
  2. $7.86$
  3. $8.63$
  4. $0.863$

Solution

If density in $\mathrm{g} / \mathrm{cm}^3$ is 0.863 density in $\frac{0.863}{\frac{1}{1000} \mathrm{dm}^3} \times \frac{1}{100} \mathrm{~kg}$ $=0.863 \frac{\mathrm{kg}}{\mathrm{dm}^3}$
