Pressure and Its Measurement
1.”
Convert each pressure to an equivalent pressure in standard atmospheres.
(a)
736 mmHg;
(b)
58.2 cm Hg;
(c)
892 Torr;
(d)
225 kPa.
The Simple Gas Laws
9.”
A sample of O
2
(g) has a volume of 26.7 L at 762 Torr. What is the new
volume if, with the temperature and amount of gas held constant, the pressure is
(a)
lowered to 385 Torr;
(b)
increased to 3.68 atm?
11.”
We want to increase the volume of a fixed amount of gas from 57.3 to 165
mL while holding the pressure constant. To what value must we change the
temperature if the initial temperature is 22 °C?
