Room temperature is often assumed to be 25 Celsius. Calculate the molar volume of an ideal gas at 25 Celsius and 1 atm pressure.

Question

Answer is 24.5L, Im trying to figure out how they got the answer. Help??

Answer 1

Use the ideal gas equation:

PV = nRT

n = number of moles = 1
P = Pressure = 1 atm
T = Temp. = 298K
R = 0.082 (when volume is in liter)

=> V = (nRT)/P
= (1*0.082*298)/1
= 24.5 L

Answer 2

Thank you so much!

Answer 3

Ry: I recommend you memorize that molar volume at 25C

Answer 4

How did u get 0.082

Answer 5

Oh constant
