Problem

A vertical tube open to air is filled with an unknown liquid to a height of

0.80\,\text{m}

. The gauge at the base reads

6.3\times10^3\,\text{Pa}

above atmospheric pressure. Calculate the density of the liquid. (Take

g = 9.8\,\text{m\,s}^{-2}

.) a)

1.3\times10^{3}\,\text{kg\,m}^{-3}

8.0\times10^{2}\,\text{kg\,m}^{-3}

6.4\times10^{2}\,\text{kg\,m}^{-3}

1.0\times10^{3}\,\text{kg\,m}^{-3}
