If two gases with pressures of 2 atm and 3 atm are mixed at a constant temperature, what will the total pressure be?A.3 atm – 2 atmB.C.2 atm + 3 atmD.2 atm 3 atmSUBMITarrow_backPREVIOUS
Solution
The total pressure of two mixed gases at a constant temperature can be found by simply adding the pressures of the two gases together. This is due to Dalton's Law of Partial Pressures, which states that the total pressure exerted by a mixture of gases is equal to the sum of the pressures that each gas would exert if it were alone.
So, in this case, the total pressure would be 2 atm (from the first gas) + 3 atm (from the second gas) = 5 atm.
Therefore, the correct answer is C. 2 atm + 3 atm.
