102.8 kPa.
Explanation:
We can use the general law of ideal gas: PV = nRT.where, P is the pressure of the gas in atm (P = ??? atm).
V is the volume of the gas in L (V = 4000 mL = 6.23 L).
n is the no. of moles of the gas in mol (n = 0.25 mol).
R is the general gas constant (R = 0.0821 L.atm/mol.K),
T is the temperature of the gas in K (T = 35ºC + 273 = 308 K).
∴ P = nRT/V = (0.25 mol)(0.0821 L.atm/mol.K)(308 K)/(6.23 L) = 1.015 atm.
To convert to kPa:multiply the pressure value by 101.325
∴ P = (1.0 atm)(101.325 kPa/1.0 atm) = 102.8 kPa.
