The molar mass of diethyl ether can be calculated using the ideal gas law equation, PV = nRT, where P is the pressure in atm, V is the volume in liters, n is the number of moles, R is the ideal gas constant (0.0821 L·atm/mol·K), and T is the temperature in Kelvin. First, convert the temperature to Kelvin: 27 °C + 273 = 300 K. Then, rearrange the ideal gas law to solve for n (moles): n = PV / RT. Substituting the given values: n = (1.11 atm * 1.06 L) / (0.0821 L·atm/mol·K * 300 K) = 0.0478 moles. Finally, calculate the molar mass: molar mass = mass / moles = 3.54 g / 0.0478 moles = 74.1 g/mol.
