A container filled with gas is connected to an open-end manometer that is filled with mineral oil.The pressure in the gas container is 763 mm Hg and atmospheric pressure is 734 mm.How high will the level rise in the manometer if the densities of Hg and mineral oil are 13.6 g/mL and 0.822 g/mL respectively?
A)1.75 mm
B)23.8 mm
C)29.0 mm
D)480 mm

The difference in pressure between the gas in the container and the atmospheric pressure is 763 mm Hg - 734 mm Hg = 29 mm Hg. To find the equivalent height in mineral oil, use the ratio of the densities: (29 mm Hg) * (13.6 g/mL) / (0.822 g/mL) ≈ 480 mm.
