Answer is: volume of helium is 244.72 liters.
m(He) = 43.7 g.
n(He) = m(He) ÷ M(He).
n(He) = 43.7 g ÷ 4 g/mol.
n(He) = 10.925 mol.
V(He) = n(He) · n(He).
V(He) = 10.925 mol · 22.4 L/mol.
V(He) = 244.72 L.
Vm - molar volume at STP.
n - amount of substance.

Before this current, the particles inside the solution are static. If a solution contain sodium chloride so when the electrical current is passed. Sodium moves to the negative electrode while chlorine moves towards positive electrode and both the atoms are separated from each other and the reaction is completed.
