It is possible to make a barometer using a liquid other than mercury.What would be the height (in meters)of a column of carbon tetrachloride at a pressure of 0.890 atm,given that 0.890 atm is equal to a 0.676 m column of mercury and the densities of mercury and carbon tetrachloride are 13.5 g/cm³ and 1.58 g/cm³,respectively. A) 5.78 m B) 0.173 m C) 0.0792 m D) 1.07 m E) 0.936 m

The height of the liquid column is inversely proportional to the density of the liquid. Using the formula $ h_1 \cdot \rho_1 = h_2 \cdot \rho_2 $, where $ h_1 $ and $ \rho_1 $ are the height and density of mercury, and $ h_2 $ and $ \rho_2 $ are the height and density of carbon tetrachloride, we find $ h_2 = \frac{h_1 \cdot \rho_1}{\rho_2} = \frac{0.676 \cdot 13.5}{1.58} \approx 5.78 $ m.
