Question

A fixed quantity of gas fills a volume of 10.6 liters at 638 torr and 83 C. Find the volume it will occupy if the pressure is 1076 torr and the temperature rises to 96 C

Answer 1

According to this formula:
(P1V1) / T1 = (P2V2) / T2

convert T from C° to Kelvin:
T1 = 83 + 273 = 356 K
T2= 96 + 273 = 369 K

convert P from torr to atm:
1 torr = 0.00131578947 atm
p1 = 0.839474 atm
P2 = 1.415789 atm
By substitution in the previous formula:
(0.839474 x 10.6 ) / (356) = ( 1.415789 x V2 ) / 369
So:
V2 = 6.5 L
