Question

What is the final pressure (expressed in atm) of a 3.05 l system initially at 724 mm hg and 298 k, that is compressed to a final volume of 2.60 l at 273

Answer 1

P2 = 778.05 mm Hg = 1.02 atm

Step-by-step explanation:

We are to find the final pressure (expressed in atm) of a 3.05 liter system initially at 724 mm hg and 298 K which is compressed to a final volume of 2.60 liter at 273 K.

For this, we would use the equation:

`(P_1V_1)/(T_1) =(P_2V_2)/(T_2)`

where P1 = 724 mm hg

V1 = 3.05 L

T1 = 298 K

P2 = ?

V2 = 2.6 L

T2 = 173 K

Substituting the given values in the equation to get:

`((724)(3.05))/(298) =(P_2(2.6))/(173)`

P2 = 778.05 mm Hg = 1.02 atm
