What is the numerical value of the gas constant R- in J `mol^(-1)` `K^(-1)` ?

What is the value of gas constant R in J mol^(-1 ) K^(-1) ?

Numerical value of universal gas constant R depends on

Numerical value of universal gas constant 'R' depends on

Fill in the blanks: The value of gas constant is …………J/mol/K

The specific heat of helium at constant volume is 12.6 Jmol^(-1)K^(-1). The specific heat of helium at constant pressure in Jmol^(-1)K^(-1) is about (Assume the temperature of the gas is moderate, universal gas constant, R=8.314 J mol^(-1)K^(-1)

Given the values of the two principal specific heats, S_P=3400 cal kg^-1 K^-1 and S_v=2400 cal kg^-1 K^-1 for the hydrogen gas, find the value of J if the universal gas constant R = 8300 J kg^-1 K^-1 .
