An organic chemist isolates a colourless liquid with the properties of cyclohexane with molar mass 84.2g/mol from a petroleum sample. She uses the dumas method and obtains the following data to determine its molar mass:
volume of flask=213ml
Temperature=100celsuis
mass of flask+gas=78.416g
mass of flask=77.834g
pressure=754torn
is the molar mass consistent with the liquid being cyclohexane? (1atm=760torn).
