If a 100. Liter balloon is filled with 4.00 moles of O 2 at a pressure of 1.50 atm what is the temperature in Celcius?

Question

A. 325 C

B. 3249 C

C. 184 C

D 457 C

Answer 1

You will need to use ideal gas law to solve this problem. PV=nRT. In this case you are looking for the temperature of the balloon. So you will set the equation to solve for T. T=PV/nR. P=1.5atm, V=100L, n=4m and R=0.0821 L*atm/moles*K. Your temperature value will come out in kelvin based on this equations. 456.76K. To get it into celsius, you will then need to subtract 273.15. Your final answer will be 183.6C which rounds up to 184 C, matching answer C.
