A manometer is connected to a gas containing bulb The open arm reads `43.7 cm` where as the arm connected to the bulb reads `15.6 cm` If the barometric pressure is 743mm mercury What is the pressure of gas in bar ? .

Explanation

To find the pressure of the gas in bar using the manometer readings and the barometric pressure, we can follow these steps:

### Step 1: Calculate the difference in mercury levels.
The difference in height between the two arms of the manometer is given by:

\[ \text{Difference} = \text{Height of open arm} - \text{Height of gas arm} \]
