A gas sample occupies 3.50 liters of volume at 20.°C. What volume will this gas occupy at 100.°C (reported to three significant figures)?

Sounds like an ideal gas problem. Have you tried?
$\frac{P_1 V_1}{T_1} =\frac{P_2 V_2}{T_2}$

(Note that we are assuming that the pressure of the gas is the same for both states. This is, of course, impossible to design, but that's Thermodynamics for you!)
