## Question:

Some elementary chemistry textbooks give the value of R, the ideal gas constant, as 0.0821l atm K^{−1}mol^{−1}.

(a) Obtain the value of R in l atm K^{−1} mol^{−1} to five significant digits.

(b) Calculate the pressure in atmospheres and in (N m^{−2} Pa) of a sample of an ideal gas with n = 0.13678 mol, V = 10.000 l, T = 298.15 K.
