The systemic name of H2O is Dihydrogen monoxide.
The mass number of aluminium hydroxide is 78 thus, the number of moles in 0.745 g is:

= 0.745/78
=0.00955moles
Therefore the 0.00955 moles should be in the 35.18 ml
therefore 1000ml of the solution will have:
(0.00955ml×1000ml)/35.18
=0.2715moles
The solution will be 0.27M hydrochloric acid
