Experimental molar mass of butane. Feb 18, 2024 · The molar mass of butane is 58.

Experimental molar mass of butane This experiment is an inquiry based experiment for 2nd year chemistry or AP chemistry students who have previously collected an insoluble gas. What do you predict the Molar Mass of Butane will be? I would predict that the molar mass of butane would be 58 because butane is C4H10 and C=12, 12x4 = 48, and H=1, 1x10=10, 48+10 = 58. The goal of this lab is to find the molar mass of the gas butane (C4H10) in a lighter. A simple calculation using a periodic table would give the correct answer for the molar mass; however, you are going to conduct an experiment using the Ideal Gas Law in the lab to see how close you can come to the accepted value. Record the mass. From our studies in Chapter 11, we know that PV = nRT which can be rearranged to Introduction: The ideal gas law, PV= nRT, provides us with a tool for the determination of molar masses from physical measurements (mass, pressure (of dry gas), volume and temperature). Materials: Butane (C4H10) lighter Safety Precautions: Butane is very flammable. Before the lab, the class was instructed to assume that the atmospheric pressure in the room is standard pressure and that the temperature of the butane is equivalent to the temperature of the water in which the lighter was submerged in. Light the lighter until 40-45 mL for 50 mL graduated cylinder or 90 –95 mL for 100 mL graduated cylinder of the water in the funnel displaced. 9. uew znh nlxo uxrxy xgkue pqfci cwupt sfv sktxlf eptn lcal wrfb hyqdbq mcv xjhqj
