Two bulbs containing different gases are connected by a stopcock. The first bulb is two liters in volume and contains gas at pressure of 1.0 atm. The second bulb is three liters in volume and contains oxygen gas at a pressure of 2.0 atm. After opening the stopcock and allowing the gas to mix, calculate the pressure of each of the gases and the total pressure of the mixture.
The thing i dont understand is do i find the number of moles of each gas before they were mixed?
