A gas occupies a volume of 0.500 L at 125 C and 0.443 atm. What mathematical expression will yield the correct temperature at 0.750 L and 0.689 atm?
 
  A) (0.689  0.750  125)/(0.443  0.500)
  B) (0.443  0.500  398)/(0.689  0.750)
  C) (0.443  0.500)/(0.689  0.750  398)
  D) (0.689  0.750  398)/(0.443  0.500)
