A student reads a barometer in the laboratory and finds the prevailing atmospheric pressure to be 675 mm Hg. Express this pressure in atmospheres, kilopascals, torrs, pounds per square inch, and pascals. Hint: 1 atm = 101.3 kPa = 760 torr = 760 mm Hg = 14.69 psi 1.013x10 Pa mm Hg atm kPa torr psi Pa 675
