An evacuated bulb of unknown volume is filled with a sample of `H_(2)` gas at a temperature `T` The pressure of the gas in the bulb is `756mm` Hg A portion of the `H_(2)` gas is transferred to a different flask and found to occupy a volume of `40.0mL` at 1.00 atn and the same temperature `T` The pressure of the `H_(2)` gas remaining in the original bulb drops to `625mm` hg at the same temperature `T` Assuming `H_(2)` is an ideal gas, what is the volume of the bulb ? .
