Using the ideal gas equation, determine the value of gas constant R. Given that one gram mole of a gas at S.T.P occupies a volume of 22.4 litres |
|
Answer» Correct Answer - `8.31 J mole^(-1) K^(-1)` Here, `R = ? V = 22.4` litre `= 22.4 xx 10^(3) m^(3)` at S.T.P, `T =273 K`, and `P=1` atmosphere `= 1.013 xx 10^(5)N//m^(2)` For one mole of gas, `PV =RT` `R = (PV)/(T) = (1.013 xx 10^(5) xx 22.4 xx 10^(-3))/(273)` `= 8.31 J mole^(-1) K^(-1)`. |
