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.
