Answer:

<u>We are given:</u>

v1 = 3.2 L                   v2 = x L

p1 = 822 torr OR 1.08 atm        p2 = 2.33 atm

t1 = t2 = 284 k

<u></u>

<u>From the Ideal gas equation:</u>

PV = nRT

Since the number of moles (n), universal gas constant (R) and Temperature (T) are constant

PV = k      (where k is a constant)

it can also be written as:

P1V1 = k --------------------------(1)

Similarly,

P2V2 = k (where k is the same constant as before)----------(2)

<u>Solving for V2:</u>

From (1) and (2):

P1V1 = P2V2

Replacing the variables

1.08 * 3.2 = 2.33 * x

x = (1.08 * 3.2)/2.33

x = 1.5 L (approx)

Therefore, the final volume of the solution will be 1.5L
