Question

At 25.0° C, a 10.00 L vessel is filled with 5.25 moles of Gas A and 7.75 moles of Gas B. What is the total pressure in atm?

Answer 1

23.12 atm

Step-by-step explanation:

First, add together the moles of the two samples:

5.25 moles + 4.20 moles = 9.45 moles

273 + 25 = 298 K for the temperature

volume is 10.0 L

Since we have moles now, we have to rearrange our ideal law equation to solve for pressure:

`P = (nRT)/(V)`

`((9.45 moles) X (0.08206) X (298 K))/(10.0 L)`

9.45 X .08206 X 298 all divided by 10.0 = 23.09202 atm (or 23.12)
