CHEMESTRY HOMEWORK HELP
1. For a certain ideal gas, the temperature is
increased from 200 K to 687 K allowing pressure, which is initially 1 atm, to vary while
the volume and number of moles of gas are
held constant. What is the new pressure?
Answer in units of atm.
2. A gas has a pressure of 1.75 atm and occupies
a volume of 6.3 L. If the gas is compressed to
a volume of 2.13 L, what will its pressure be,
assuming constant temperature?
Answer in units of atm.
3. A sample of argon gas occupies a volume of
253 mL at 18 ◦C. What volume will the
gas occupy at 63.8548 ◦C, assuming constant
pressure?
Answer in units of mL.
