pressure in the flask
« on: February 29, 2008, 10:57:36 PM »
When 0.675 L of Ar at 1.20 atm and 227°C is mixed with 0.259 L of O2 at 501 torr and 127°C in a 400 mL flask at 27°C, what is the pressure in the flask?

Please, help me out from this question!

You have to calculate total number of moles of gases.
