Chapter 9: Q6 E (page 506)

A typical barometric pressure in Kansas City is 740 torr. What is this pressure in atmospheres, in millimeters of mercury, and in kilopascals?

Short Answer

Expert verified
  1. 740Torr = 0.9736 atm
  2. 740Torr = 740 mm of Hg
  3. 740Torr = 98.65 KPa

Step by step solution

01

Define pressure

Force applied perpendicular to an object's surface per unit area across which that force is spread is known as pressure.

02

Explanation

a) Converting Torr pressure to atm.

1 Torr = 0.001315 atm.

740 Torr = (740) x (0.001315) atm.

=0.9736 atm

Therefore, 740 Torr of Hg is equal to 0.9736 atm.

b) Converting Torr pressure to atm.

1 Torr = 1mm of Hg

740 Torr = (740) x (1) mm of Hg.

=740 mm of Hg

Therefore, 740 Torr is equal to 740mm of Hg.

c) Converting torr to kPa pressure.

1 Torr = 0.1333 Kpa.

740 Torr = (615) x (0.1333) Kpa.

= 98.65 Kpa.

Therefore, 740 Torr is equal to 98.65 Kpa.

Why is it necessary to use a non-volatile liquid in a barometer or manometer?

How many moles of gaseous boron trifluoride, \({\rm{B}}{{\rm{F}}_{\rm{3}}}\), are contained in a 4.3410\({\rm{L}}\)bulb at 788.0K if the pressure is1.220 atm? How many grams of \({\rm{B}}{{\rm{F}}_{\rm{3}}}\)?

Question: Describe what happens to the average kinetic energy of ideal gas molecules when the conditions are changed as follows:

(a) The pressure of the gas is increased by reducing the volume at constant temperature.

(b) The pressure of the gas is increased by increasing the temperature at constant volume.

(c) The average velocity of the molecules is increased by a factor of \({\rm{2}}\).

Calculate the density of Freon \(12,{\rm{C}}{{\rm{F}}_2}{\rm{C}}{{\rm{l}}_2}\), at \({30.0^\circ }{\rm{C}}\) and \(0.954\;{\rm{atm}}\).

Question: When two cotton plugs, one moistened with ammonia and the other with hydrochloric acid, are simultaneously inserted into opposite ends of a glass tube that is 87.0 cm long, a white ring of \({\rm{N}}{{\rm{H}}_{\rm{4}}}{\rm{Cl}}\) forms where gaseous \({\rm{N}}{{\rm{H}}_{\rm{3}}}\) and gaseous \({\rm{HCl}}\) first come into contact. (Hint: Calculate the rates of diffusion for both \({\rm{N}}{{\rm{H}}_{\rm{3}}}\) and \({\rm{HCl}}\), and find out how much faster \({\rm{N}}{{\rm{H}}_{\rm{3}}}\) diffuses than \({\rm{HCl}}\).) \({\rm{N}}{{\rm{H}}_{\rm{3}}}{\rm{(g) + HCl(g)}} \to {\rm{N}}{{\rm{H}}_{\rm{4}}}{\rm{Cl(s)}}\)

At approximately what distance from the ammonia moistened plug does this occur?
