Answer:
0.9925 atm.
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 = 42.5 L).
n is the no. of moles of the gas in mol (n = 1.52 mol).
R is the general gas constant (R = 0.0821 L.atm/mol.K),
T is the temperature of the gas in K (T = 65°C + 273 = 338.0 K).
∴ P = nRT/V = (1.52 mol)(0.0821 L.atm/mol.K)(338.0 K)/(42.5 L) = 0.9925 atm.
