The stopcock connecting a 3.06 l bulb containing methane gas at a pressure of 9.61 atm, and a 6.65 l bulb containing oxygen gas at a pressure of 1.75 atm, is opened and the gases are allowed to mix. assuming that the temperature remains constant, the final pressure in the system is atm.

Answer : The final pressure in the system is 4.22 atm.

Explanation :

First we have to calculate the moles of methane.

where,

P = pressure of gas = 9.61 atm

V = volume of gas = 3.06 L

T = temperature of gas = T

= number of moles of methane gas = ?

R = gas constant

Now put all the given values in the ideal gas equation, we get:

Now we have to calculate the moles of oxygen gas.

where,

P = pressure of gas = 1.75 atm

V = volume of gas = 6.65 L

T = temperature of gas = T

= number of moles of oxygen gas = ?

R = gas constant

Now put all the given values in the ideal gas equation, we get:

Now we have to determine the final pressure in the system after mixing the gases.

where,

= final pressure of gas = ?

= final volume of gas = (3.06 + 6.65)L = 9.71 L

T = temperature of gas = T

R = gas constant

Now put all the given values in the ideal gas equation, we get:

Therefore, the final pressure in the system is 4.22 atm.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
