Question

a gas is contained in a thick walled balloon. when the pressure changes from 417 mm hg to 576 mm hg, the volume changes from l to 4.78 l and the temperature changes from 497 k to 386k

Answer 1

8.50 L

Step-by-step explanation:

Answer 2

we can use the combined gas law equation to solve for the initial volume

`(P1V1)/(T1) = (P2V2)/(T2)`
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
substituting the values in the equation

`(417 mmHg*V)/(497 K) = (576mmHg*4.78L)/(386K)`
V = 8.50 L
the initial volume is 8.50 L
