At 25.0 ° C, a 10.00 L vessel is filled with 5.25 moles of Gas A and 7.05 moles of Gas B. What is the total pressure?

P = 30.1 atm

Explanation:

Given dа ta:

Temperature of vessel = 25°C

Volume of vessel = 10.00 L

Moles in vessel = A + B = 5.25 mol + 7.05 mol = 12.3 moles

Total pressure inside vessel = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P = Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm. L / mol. K

T = temperature in kelvin

Now we will convert the temperature.

25+273 = 298 K

P = nRT/V

P = 12.3 mol * 0.0821 atm. L / mol. K * 298 K / 10.00 L

P = 300.93 / 10.00 L

P = 30.1 atm
