The pressure of a sample of gad is measured at sea level with a closed-end manometer. The liquid in the manometer is mercury, and the liquid level on the right side is 34.6 cm higher than the liquid level on the left side (assume the gas chamber is on the left side).rndetermine the pressure of the gas in torr.rn346 torrrn46,100 torrrn3.46 torrrn0.461 torr

Accepted Answer

The pressure of the gas is equal to the pressure exerted by the mercury column. The pressure exerted by the mercury column is calculated as follows:
Pressure = Density of mercury
Gravity
Height of mercury column
Density of mercury = 13.6 g/cm³
Gravity = 9.8 m/s²
Height of mercury column = 34.6 cm = 0.346 m
Pressure = 13.6 g/cm³
9.8 m/s²
0.346 m = 461 torr
Therefore, the pressure of the gas is 461 torr.
