Web10 feb. 2024 · Using the properties of its vapor phase, calculate its molar mass using the ideal gas law. In this experiment, students will determine the molar mass of an unknown volatile liquid by measuring the properties of its vapor phase after heating. The liquid is heated until it is completely vaporized. WebMolar concentration allows us to convert between the volume of the solution and the moles (or mass) of the solute.
