1. The problem statement, all variables and given/known data In the above manometer, attached to a sample of gas, the difference in the height of the mercury levels is 30.0mm. The barometric pressure is 754.0mm Hg. What is the pressure of the gas sample in kiloPascals ? ( The above figure is not drawn to scale, but the relative heights of the right and left columns of mercury are correctly shown ) Enter a numeric answer only, no units. 2. Relevant equations 1)If The height of the mercury level at the gas side is higher. This means that P(atm) > P(gas), So Pgas = 754 - 30 = 724 mmHg. 2)If The height of the mercury level at the atmosphere side is higher. This means that P(atm) < P(gas), So Pgas = 754 + 30 = 780 mmHg. 3. The attempt at a solution 1 mmHg = 133.3 Pa So: 724*133.3 = 96509.2 OR 780*133.3 = 103974 what did i do wrong ?
