Aluminum Sulfide Reacts with Water to Form Aluminum Hydroxide and Hydrogen

 Aluminum sulfide reacts with water to form aluminum hydroxide and hydrogen sulfide by the following reaction $\mathrm{Al}_{2} \mathrm{~S}_{3}+6 \mathrm{H}_{2} \mathrm{O} \rightarrow 2 \mathrm{Al}(\mathrm{OH}) _{3}+3 \mathrm{H}_{2} \mathrm{~S}$ If 25 g of aluminum sulfide is reacted with 25 g of water how many moles of hydrogen sulfide will be formed? 

A)  0.12 moles
B)  0.50 moles
C)  0.78 moles
D)  2.0 moles
E)  3.0 moles
