Answer:
0.257 L
Explanation:
The values missing in the question has been assumed with common sense so that the concept could be applied
Initial volume of the AICI3 solution
Initial Molarity of the solution
Final molarity of the solution
Final volume of the solution
From Law of Dilution,
Final Volume of the solution 
You have to use the molar volume of gas which is 22.4L/mol at STP. To find the number of moles of from a given volume of gas at STP, you need to divide the given volume by 22.4L/mol.
44.4L/22.4L/mol=1.98mol of gas
Explanation:
The grey powder of silver ( I ) oxide i.e. Ag₂O breaks down to give a metal called the silver metal and an odorless , colorless gas , which is the oxygen gas .
The balanced chemical reaction is as follows -
Silver oxide -----> Silver + oxygen
Ag₂O ------> Ag (s) + O₂ (g)
The balanced reaction is -
2 Ag₂O (s) ------> 4 Ag (s) + O₂ (g)
