, Show the calculation of the new volume of a gas sample which has an original volume of 660 ml
when collected at 660 mm and 38oC when the pressure increases to 780 mm and the temperature
increases to 45oC.
Your Answer:
660/1000 = .66L
38+273 = 311K
45+273 = 318k
660mm/760 = 0.8684210526 atm
780mm/760 = 1.026315789 atm
pxv/ t = pxv/ t
0.8684210526 X . = 1.026315789 atm x V / 318
0.5731578947/311 = 1.026315789V/318
0.5731578947 x 318 = 1.026315789V x 311
182.2642105 = 319.1842104 V
0.5710314125 L= v
