The vapor pressure of bromine,

(a) How many grams of bromine will be present as a gas if liquid bromine is poured into an evacuated 2.00-L flask at 25°C?

(b) If 2.00 g of bromine are used, what is the final pressure in the flask? Will there be liquid in the flask?

(c) If 2.00 g of bromine are put into an evacuated 750.0-mL flask at 25°C, what is the final pressure in the flask? Will there be any liquid in the flask?
