Answer:
Approximately .
Explanation:
Look up the density of carbon tetrachloride,
, and glycerol:
- Density of carbon tetrachloride: approximately
.
- Density of glycerol: approximately
.
Let denote the gravitational field strength. (Typically
near the surface of the earth.) For a column of liquid with a height of
, if the density of the liquid is
, the pressure at the bottom of the column would be:
.
The pressure at the bottom of this carbon tetrachloride column would be:
.
Rearrange the equation for
:
.
Apply this equation to calculate the height of the liquid glycerol column:
.
