The volume of the gas can be calculated by finding the difference between the initial volume of water and the final volume of water after the gas has displaced some of it. 
Initial volume of water = 752 mL 
Final volume of water = 305 mL 
Volume of gas = 752 mL - 305 mL = 447 mL 
Therefore, the answer is (C) 447 mL.
