Answer:
0.612 atm
Explanation:
Use the Universal Gas Law:
PV = nrT
Where P is pressure, V is volume, n is the number of moles, r is the universal gas constant, and T is temperature in K.
Plug in your given values:
(P)(25.0) = (0.5)(0.0821)(373)
Solve for P:
P = 0.612466
--> Round to sigfig:
P = 0.612
* The universal gas constant I used was Latm/molK. If the answer needs to be in Kpa or Torr, you would need to convert it again.
Hope this helps!
