Molar Mass of Volatile Liquid
You can add a content to what I have given as below.

1. Introduction
▶ Give a explanation for Ideal gas equation. (Summary of what the experiment was about.)

This experiment is about to know the molar mass of volatile liquid. First, measure the mass of vapor of a volatile liquid and use the ideal gas law to determine the number of moles of gas in sample. Then, determine the molar mass of the volatile liquid.
Since we got the mass of condensed vapor, pressure, temperature, and volume of the test tube, we can get the mole of the liquid by ideal gas law. With the number of the mole of the liquid, we can get the molecular mass of the liquid by the mass of the condensed liquid divide by the number of the mole.
Ideal gas law is PV〓nRT. P means pressure, V is volume, n is the number of mole, R is gas constant, T is absolute temperature. This equation is combined three law that Boyle’s law,…(To be continued )
