If the value of molar gas constant is 8.3 J/mole-K, the n specific gas constant for hydrogen in J/mole-K will be

The correct option is 4.15.

Step-by-step derivation:

The specific gas constant ($R_s$) of a gas is related to the universal molar gas constant ($R$) and the molecular mass ($M$) of the gas by the following formula:
$R_s=\frac{R}{M}$

We are given the following values:
Molar gas constant, $R=8.3\text{J/mol-K}$
Molecular mass of hydrogen gas (${\text{H}}_2$), $M=2\text{g/mol}$

Substitute the given values into the equation to calculate the specific gas constant for hydrogen:
$R_s=\frac{8.3}{2}=4.15$

Thus, the value of the specific gas constant for hydrogen is 4.15.
