Question

What volume is occupied by 0.25 mol of carbon dioxide gas at 25 °C and 371 torr?

Answer 1

Answer: Volume = 12.48 lit.

Explanation: n = 0.25 mole

                      T = 25+273 = 298K

                       P = 375 torr  [ 1 torr = 1 mm Hg ]

                           = 375 mm Hg

                           = 375/ 760

                           = 0.49 atm

We have, PV = nRT

                  V = nRT / P

  By putting the values we get the value of V = 12.48 lit. ans
