Avogadro Lab Report

In this lab, we will attempt to derive Avogadro’s number by forming a monolayer of Stearic Acid on the surface of a dish of water. The value of Avogadro’s number, which is known as the mole, equals 6.022*〖10〗^23. As the result of the high energy found on the surface of water and the hydrogen bonds in water, surface tension plays a key role in this experiment. The monolayer we anticipate making is possible because the tiny hydrophilic poles of Stearic Acid latch onto the molecules, but the larger hydrophobic portion of Stearic Acid prevents complete immersion. Thus, producing a monolayer. To derive Avogadro’s number from the data collected in the lab, we must divide the volume of the Stearic Acid by the area of the water surface.
