Answer:
1.6 atm
Explanation:
We are given that total pressure of mixture of two gases=5.7 atm
Partial pressure of one gas=4.1 atm
We have to find the partial pressure of other branch.
We know that Dalton;s law of partial pressure
It states that pressure exerted by mixture of gases is equal to sum of partial pressure exerted by gases in mixture.
Let x bet the pressure exert by other gas
Apply this law
Total pressure=4.1+x
Hence, the partial pressure of other gas=1.6 atm.

Hello!
In this case, we can divide the problem in two steps:
1. Dilution to 278 mL: here, the initial concentration and volume are 1.20 M and 52.0 mL respectively, and a final volume of 278 mL, it means that the moles remain the same so we can write:
So we solve for C2:
2. Now, since 111 mL of water is added, we compute the final volume, V3:
So, the final concentration of the 139 mL portion is:
