A 2.01 L flask containing 2.31 g of helium gas (molar mass = 4.003 g/mol) is separated by a stopcock from a 3.16 L flask containing 3.08 g of fluorine gas (molar mass = 38 g/mol). After the stopcock is opened the total pressure is 625 mm Hg. What was the pressure (reported to three significant figures) of the helium before the stopcock was opened?
