When Na2S2O3 dissolves in water, it dissociates into Na+ and S2O32- ions:
Na2S2O3 ⇒2Na+ + S2O32-
So 1 mole of Na2S2O3 generates 2 Na+s.
The moles of Na2S2O3 = volume of Na2S2O3 * molarity of Na2SO3 = 0.01L * 0.15mol/L = 0.0015 mol.
Therefore, the moles of Na+ in the solution = 0.0015mol * 2 = 0.003 mole.

Answer : Option A)
45.5%
Explanation : We use the formula of calculating energy efficiency which is as,
η (in %)= [
] X 100
where η is energy efficiency,
and P values are for energy out and in.
So plugging the given values, we get,
η (in %) = (11825.5 / 25978.8) X 100 =
45.5 %
