Question

At 25.0° C, a 10.00 L vessel is filled with 5.25 moles of Gas A and 4.10 moles of Gas B. What is the total pressure in atm?

Answer 1

22.9atm

Step-by-step explanation:

Partial pressures should add to the total pressure. Knowing that we can use the ideal gas law PV=nRT where

P = pressure

V = volume

n = moles of gas

R = gas constant (0.08206
`((L)(atm) )/((mol)(K))`)

T = temp in Kelvin (Celcius + 273)

rearranging this formula for pressure we get

P = (nRT)/V

P = ((5.25+4.10)x0.08206x298)/(10.00)

P = 22.9atm
