4. A system contracts from an initial volume of 15.0 L to a final volume of 10.0 L under a constant external
pressure of 0.800 atm. The value of w, in J, is

When detern
ing the
mass of a
liquid,
ras in a hurry and did
not allow enough time for the temperature of the flask to reach the temperature of the
boiling water bath. The student recorded the temperature of the gas as 100.0°C when it
was only 80.0°C, Is the molar mass calculated by the student higher or lower than the
accepted molar mass, or does this error have no effect on the calculated result? Briefly

b) If the student assumed the volume of the flask was 125 mL (as marked by the side of the
flask) rather than measuring the volume experimentally, would the unknown's calculated
molar mass be too high, too low, or unaffected? Explain.

If pressure is expressed in atmospheres and volume is expressed in liters, PAV has units of L atm (liters x atmospheres). Remember
that 1 atm = 101,325 Pa, and that 1 L = 1 dm. Use this information to determine the number of joules corresponding to 5 L atm.
