ON a rainy day, a barometer reads 739 mmHg. Convert this value to atomospheres

[From: ] [author: ] [Date: 12-03-05] [Hit: ]
What is the pressure in millimeters of mercury?--1. c.)What is the pressure (in atmostpheres) of the gas inside the container connected to an open-end, mercury filled manometer as shown in the picture? The atmospheric pressure is 0.......
-- 1.b.) a closed container is filled oxygen. The pressure in the container is 415 kPa. What is the pressure in millimeters of mercury?

--1. c.)What is the pressure (in atmostpheres) of the gas inside the container connected to an open-end, mercury filled manometer as shown in the picture? The atmospheric pressure is 0.95 atm.

Thanks!

Simple. 739 mmHg * 1 atm / 760 mm Hg. Do the math. It's just a simple pressure conversion.
b) convert from kPa to Pa (1000 Pa = 1 kPa), then from that to atmospheres is 101,325 Pa = 1 atm.
c) 0.95 atm. 1 atm = 760 mm Hg.

If you are having trouble enough with these type of questions that you have to ask people on yahoo answers, just wait until you get to Ideal gas laws. You end up with things that have to be in units of Kelvin Atmosphere Mol Liters. o_0 Memorize those conversions now before the problems actually get hard!
