Container a (with 150mL) contains a gas with an unknown pressure. Container b (with volume 250mL) contains a gas under 628 mm Hg of pressure. Container C (with volume 350mL) contains a gas under 437mm Hg of pressure. if all these gases are put into container d (with volumer 300mL) giving it 1439 mm Hg of pressure, find the original pressure of trhe gas in the container.
