QUESTION:

Given a barometric pressure of 751.5 mmHg, calculate the pressure of each gas sample as indicated by the manometer.

ANSWER:

Problem 30EGiven a barometric pressure of 751.5 mmHg, calculate the pressure of each gas sample asindicated by the manometer. Step by step solutionStep 1 of 2In the given image(a), the mercury level is higher in the left side then compared to the right side.Sinc, atmospheric pressure is greater than the gas pressure.The height difference between the two levels = 2.0 cmConvert the centimeter into millimeters.The difference height between two levels =20 mm HgThe barometric pressure = 751.5 mm HgLet’s calculate the sample pressure.Sample pressure = Atmospheric pressure - Difference in height between the two levels\nTherefore, sample gas pressure is 731 mm Hg.
