Experiment 2 - Lab Report Example comparison for Archimedes buoyancy force is Fb = g(mobject mair), where Fb = buoyancy force, g = gravitational acceleration, and m = mass. On the other hand, Avogadros laws allows for the ending of a blow out volume at a given density. Equation for Avogadros law is hoagy mass/densitySTP = 22.415L/mole. By determining the volume and mass of any gas, it becomes easy to deduce a gas molar mass (Peck 68). This experiment involved determining the molar masses of hydrogen and helium gases that atomic number 18 less dense than air.Prior to commencement of the experiment, appropriate safety requirements were performed. First, use of safety goggles and research lab coats was prioritized. Secondly, water spilled on the floor was wiped in order to prevent slippage of students during the experiment. Finally, any chance of hydrogen inflammation was considered, especially adherence to the use of fumed hood and prevention of static electricity.After the safe ty considerations, adjectival steps of the experiment were performed. The volume of the agglomerate was measured using a graduated cylinder. Simultaneously, the balloon was inclined(p) by inflating it with either hydrogen or helium and subsequently weighed. Either excess balloon was faded off or additional pieces of strings added to the balloon setup until the balloon could float in air. Next, the pitcher setup was performed by immersion into water and the balloon gas transferred into the immersed pitcher. Finally, the gas volume was measured in concert with other relevant parameters like air pressure and environmental temperature. As a means of facilitating union and precision, three trials were performed for both hydrogen and helium. Data and results from each step of the experiment were recorded in the poll below.Based on the data collected during the experiment, the calculated average molar mass of hydrogen is 2.107 g/mol while that of helium is 1.14 g/mol.
