Ans:-

A coulomb is "1.036 \\times10^{-5}" mole of elementary electric charges (electrons, protons, or singly charged ions).

"1" mole of any ideal gas is "22.4 liters" at STP. Hydrogen gas is "H_2" and very close to an ideal gas at STP.


"\\Rightarrow" "3.0000\\times10^4" "Coulomb" x "1.036 \\times10^{-5}" Mole/Coulomb = "3.108 \\times10^{-1}" Mole (of H)


"\\Rightarrow" "0.3108" Mole (H) "\\times" "\\dfrac{1\\times{H_2}\n}{2\\times{H}}" "=" "0.1554 mole (H_2)"


"\\Rightarrow" "22.4\\dfrac{liters}{mole}\\times0.1554 mole" "= 3.481 liters" . ("H_2" at STP)
