What volume of hydrogen gas measured at 27celcius and 723 torr may be prepared by the reaction of 8.88 grams of gallium with an excess of hydrochloric acid?
Ga+ HCl ==> GaCl3 + H2
Ga+ HCl ==> GaCl3 + H2

Balance the reaction...
2Ga + 6HCl yields 2GaCl3+2H2
so you get a mole of Hydrogen for each mole of Ga.
How many moles of Gallium is 8.88 grams?
Now, convert that number of moles to volume H2.
Volume= nRT/P
