Moles of "N_2O" = "given \\ mass \\over molar \\ mass"

="{0.33\\over 44 } = {3\\over 4}mole"



Balanced equation


"NH_4NO_3(s) \\rightarrow N_2O(g) + 2H_2O(l)"


We can see that 1 mole "NH_4NO_3" Produce 1 mole "N_2O" and 2 mole "H_2O"


So "{3\\over 4}" mole "NH_4NO_3" Produce "{3\\over 4}" mole "N_2O" and "{6\\over 4}" mole "H_2O"


Mass of "H_2O" = moles × molar mass

= "{6\\over 4}\u00d718 \\ g"

Answer = "\\boxed{27 g}"
