The pressure of an unknown gas is measured with a manometer. Instead of mercury the manometer is filled with a liquid (X) whose density is 0.553 g/cc. The pressure is measured as 653 mmX. What is the pressure in mmHg?

To find the pressure in mmHg, we need to convert the given pressure from mmX to mmHg.
First, let's understand the concept of pressure measurement using a manometer. A manometer measures the pressure difference between two sources, which can be expressed as the difference in the level of liquid (in this case, liquid X) in each arm of the manometer. The difference in liquid level is directly proportional to the pressure difference.
In this case, the manometer is filled with a liquid with a density of 0.553 g/cc (grams per cubic centimeter). However, to convert the units to mmHg, we need to know the conversion factor between the density of the liquid (X) and the density of mercury.
The conversion factor between densities can be given by the equation:
(density of liquid X)/(density of mercury) = (height of mercury column)/(height of liquid X column)
Unfortunately, without knowing the corresponding height of the mercury column, we cannot directly convert the density of liquid X to a conversion factor. Therefore, we are unable to calculate the pressure in mmHg.
