Since the gas it is getting compressed with a change on temperature, we consider that the pressure is constant, and of course the number of mole is constant (same gas), therefore, from the $PV=nRT$ we can say:

$V/T=" constant"$

Therefore, $(V_1)/(T_1)=(V_2)/(T_2)=>T_1=V_1xx(T_2)/(V_2)$

$=>T_1=12cancel(L)xx(300K)/(8cancel(L))=450K$

Oxygen gas is at STP when it occupies a volume 5.5 liters. To what temperature should it be raised to occupy a volume of 9.0 liters?

And this is old $"Charles' Law..."$ Now $"STP"$ specifies (depending on your syllabus) $298*K$ and (near to) $1*atm$... Given $VpropT$, $V=kT$...solving for $k$, $k=V/T$...but this should apply at all temperatures...

Chlorine gas occupies a volume of 1.20 liters at 720 torr pressure. What volume will it occupy at 1 atm pressure? Assume that temperature remains the same.

And $1*atm-=760*mm*Hg$ or rather $1*atm$ will support a column of mercury that is $760* mm$ high...and I truly hope you have seen such a column because the health and safety...

A gas occupies a volume of 444 mL at 273 K and 79.0 kPa. What is the final kelvin temperature when the volume of the gas is change 880 mL and the pressure is changed to 38.7 kPa?

Using the you can solve for your missing variable. $(P1V1)/(T1)=(P2V2)/(T2)$ P1 = 79.0 kPa V1 = 444 mL T1 = 273 K P2 = 38.7 kPa V2 = 880...

What steps and formulas would you use to solve the question "At what Kelvin temperature will a sample of gas occupy 12 liters if the same sample occupies 8 liters at 27 °C?"

You'd use , which links an ideal gas' volume to its temperature if pressure and number of moles are kept constant. The mathematical formula is this $V_1/T_1 = V_2/T_2$...

A sample of carbon dioxide gas at a pressure of 1.07 atm and a temperature of 166 °C, occupies a volume of 686 mL. If the gas is heated at constant pressure until its volume is 913 mL, the temperature of the gas sample will be ? °C.

The idea here is that the volume and the temperature of a gas have a direct relationship when the pressure and the number of moles of gas are being kept...
