Answer:

16.89 atm.

Explanation:

Step 1:

Data obtained from the question

Number of mole (n) = 2.3 mol

Temperature (T) = 40°C = 40°C + 273 = 313K

Volume (V) = 3.5L

Pressure (P) =..?

Gas constant (R) =0.0821 atm.L/Kmol

The pressure exerted by the gas can be obtained by using the ideal gas equation as shown below:

PV = nRT

Divide both side by V

P = nRT /V

P = 2.3 x 0.0821 x 313 / 3.5

P = 16.89 atm.

Therefore, the pressure exerted by the gas is 16.89 atm.
