A student reads a barometer in the laboratory and finds the prevailing atmospheric pressure to be 705 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 Ра 705 Submit Answer Retry Entire Group 2 more group attempts remaining Previous Next

Three samples of three different gases are listed in the table below. All the samples contain exactly 1 mole of gas and are at a temperature of 0.0°C. For each sample, decide whether the gas can be reasonably described as an ideal gas. If the gas isn't ideal, decide the most important reason why it isn't. 圖 pressure volume If not ideal, the most sample ideal? (atm) (L) important reason why not: olo O yes O There are attractions between the particles. A 2.9 10.0 O no O The particles don't have zero volume. O yes O There are attractions between the particles. В 1.3 20.0 O no O The particles don't have zero volume. O yes O There are attractions between the particles. 0.60 30.0 O no O The particles don't have zero volume. ? Explanation Check O 2020 McGraw-Hill Education. All Rights Reserved.
