Answer : The number of moles of hydrogen gas is, 0.033 mole

Explanation : Given,

Moles of sodium = 0.066 mole

The balanced chemical reaction will be,

2Na(s)+2H_2O(l)\rightarrow 2NaOH(aq)+H_2(g)

From the balanced chemical reaction, we conclude that 2 moles of sodium  react with 2 moles of water to give 2 moles of sodium hydroxide and 1 mole of hydrogen has as a product.

As, 2 moles of sodium react to give 1 mole of hydrogen gas

So, 0.066 mole of sodium react to give \frac{1}{2}\times 0.066=0.033 moles of hydrogen gas

Therefore, the number of moles of hydrogen gas is, 0.033 mole

Base on my research the complete reaction of hydrogen and sodium are form by this equation  2Na + 2H2O = 2NaOH +H2 If we base from this equation it shows you already the ratio of the moles of the product and reactants taking part in the reaction

1 mole of Na r/w 1 mole of water to produce .5 mole of Hydrogen 

Therefore, .066 mole of Na produces .033 moles of H2
