To calculate the height of the column of glycerin needed to balance normal atmospheric pressure, use the equation: p = ρgh. In this equation, p represents the atmospheric pressure, ρ is the density of glycerin, g is the acceleration due to gravity, and h is the height of the column of glycerin.
As given, p = 101300 Pa and g = 9.8 N/kg. However, the density of glycerin (ρ) is missing from the question. Without knowing the density, it is not possible to calculate the height (h). Therefore, I don't know the answer.
