Density and pressure — practice question

$1.5\,\text{m}^3$ of water is combined with $0.50\,\text{m}^3$ of alcohol. Water has a density of $1000\,\text{kg m}^{-3}$ and alcohol has a density of $800\,\text{kg m}^{-3}$. Determine the density of the mixture when its volume is $2.0\,\text{m}^3$?

  • A$850\,\text{kg m}^{-3}$
  • B$900\,\text{kg m}^{-3}$
  • C$940\,\text{kg m}^{-3}$
  • D$950\,\text{kg m}^{-3}$
