Find the nearest torr?


(a) Convert 1.05 bar to torr, using the relationships 1 bar = 105 Pa and 1 atm = 1.013×105 Pa = 760 torr. Express your answer to the nearest torr.
 (b) There is a photograph of a dial-type barometer in the textbook, calibrated in both millibars and millimeters of mercury. On this barometer's scales, 1000 millibars (1 bar) appears to be approximately equal to 750 mm (750 torr) of mercury. Is this approximation good to the nearest torr?
(c) The pressure inside a manometer vessel is 1.560e+5 Pa. How high is the column of mercury in the open tube of the manometer?
