The pressure of a sample of gas is measured at sea level with an open-end mercury manometer, and the liquid level is 13.7 cm higher on the left side than the liquid level on the right side (assume the gas chamber is on the left side).

Assuming atmospheric pressure is 760.0 mm Hg, determine the pressure of the gas in mm Hg.
