1. A particular gas exerts a pressure of 731 mmHg.
What is this pressure in units of atmospheres?
Note that 1 atm = 760 mmHg
2. A flexible vessel contains 43 L of gas where the
pressure is 1.3 atm. What will the volume be when the pressure is
0.61 atm, the temperature remaining constant?
3.The volume of a sample of gas measured at 35.0°C and 1.00 atm
pressure is 2.00 L. What must the final temperature be in order for
the gas to have a final volume of 3.00 L at 1.00 atm pressure (that
is, pressure remains constant)?
4.
A 23.6 -L sample of nitrogen at 4.45 atm and 23°C is
simultaneously expanded to 50.8 L and heated to 37°C. What is
the new pressure of the gas?
Note that K = °C + 273
5.
How many moles of gas are in a gas sample occupying 0.816 L at
127 mmHg and 22°C?
Note that: R = 0.0821 L • atm/K • mol
Note that: 1 atm = 760 mmHg
Note that K = °C + 273
6.
A 3.74-L cylinder contains 4.17 g of methane,
CH4 (Molar Mass: 16.04 g/mol) at a pressure of 3020
mmHg. What is the temperature (in Celsius) of the gas?
Note that: R = 0.0821 L • atm/K • mol
Note that: 1 atm = 760 mmHg
Note that K = °C + 273
7. Which of the following pairs contain both exothermic
processes?
8. Which state of matter has the weakest attractive forces
between its molecules?
9.How many moles are contained in 5.33 L of
O2 at standard temperature and pressure (STP)?
Note that K = °C + 273
