A 1.00 L flask containing 450 torr of H2 is connected to and mixed with a second flask with a volume of 0.500 L containing 250 torr N2. What is the final pressure of the resulting mixed gas system?
a) 250 torr
b)383 torr
c) 450 torr
d) 575 torr
e) it cannot be determined
To find the final pressure of the mixed gas system, we need to use Dalton's Law of Partial Pressures.
According to Dalton's Law, the total pressure of a mixture of gases is equal to the sum of the partial pressures of the individual gases.
In this case, the partial pressure of H2 is 450 torr and the partial pressure of N2 is 250 torr.
To find the final pressure, we add the partial pressures together:
Final pressure = Partial pressure of H2 + Partial pressure of N2
Final pressure = 450 torr + 250 torr
Final pressure = 700 torr
Therefore, the final pressure of the resulting mixed gas system is 700 torr.
None of the given answer choices match the correct answer.
To find the final pressure of the resulting mixed gas system, we can use Dalton's law of partial pressures. According to this law, the total pressure exerted by a mixture of non-reacting gases is equal to the sum of the partial pressures of each individual gas.
In this question, we have two separate flasks, one containing H2 and the other containing N2. The partial pressure of H2 is given as 450 torr, and the partial pressure of N2 is given as 250 torr.
To find the total pressure, we need to add these partial pressures together.
Total Pressure = Partial Pressure of H2 + Partial Pressure of N2
Total Pressure = 450 torr + 250 torr
Total Pressure = 700 torr
Therefore, the final pressure of the resulting mixed gas system is 700 torr.
However, none of the given answer choices match this result. It seems there may be an error in the question or answer choices.
Use PV = nRT
Calculate n for each container, add the number of mols to get the sum, plug that back into PV = nRT and solve for pressure. You don't have a T listed but I used 273. Actually, I think you may use any T you wish as long as you keep it constant throughout. I get one of the answers. (Hint: you KNOW it isn't 250 and you KNOW it isn't 450).
