An open end manometer constructed from a U-shaped tube was operated using an oil which has a density of 1.088 g ml-1. In a particular measurement, the level in the end connected to the gas manifold, on which the experiment was being conducted, measured 79.2 cm above the U-neck. The outside end (to the atmosphere) was 23.8 cm above the U-neck. the outside aire pressure in the laboratory was measured as 754 torr. what is the pressure in the gas manifold? For reference, the density of mercury is 13.533 g ml-1 at room temperature.
a) 42.0 torr
b) 230 torr
c) 272 torr
d) 516 torr
e) 712 torr
