Question

1a. A prevailing
pressure of one standard atmosphere will support a column of
mercury 760 mm in height. **Liquid gallium** has a density of **6.20** g/mL.
The height of a column of **liquid gallium** that one standard atmosphere can support is
**____mm.**

The density of liquid mercury is 13.6 g/mL.

**1b.** A sample of **hydrogen** gas
at a pressure of **0.727** atm and a temperature of
**28.9 °**C, occupies a volume of
**19.3** liters. If the gas is **allowed to
expand** at constant temperature to a volume of
**26.0** liters, the pressure of the gas sample will
be ____**atm.**

**1c.** A sample of **argon** gas at a
pressure of **0.588** atm and a temperature of
**22.6 °**C, occupies a volume of
**12.0** liters. If the gas is
**compressed** at constant temperature to a volume of
**9.38** liters, the pressure of the gas sample will
be atm.

Answer #1

1a

P-mercury = density of Hg * gravity * height

P-Gallium = density of Ga * gravity * height

then

P-Gallium =P-mercury

density of Ga * gravity * height = density of Hg * gravity * height

density of Ga * * height = density of Hg * * height

6.20 * height = 13.60 * 760

height of Ga = 13.60 * 760/6.20 = **1667.09 mm
Ga**

Q2

P1V1/T1 = P2V2/T2

T1 = T2 so

P1V1= P2V2

0.727*19.3 = P*26

P2 = 0.727*19.3 /26 = 0.5396 atm

Q3

P1V1 = P2V2

substitute

0.588 * 12 = P*9.38

P =0.588 * 12 /9.38

P = 0.75223 atm

A prevailing pressure of one standard atmosphere will support a
column of mercury 760 mm in height. Liquid n-propyl iodide has a
density of 1.75g/mL. The height of a column of n-propyl iodide that
one standard atmosphere can support is________ mm.
The density of liquid mercury is 13.6 g/mL.
