Measuring Mass with The Analytical Balance

Here is another video that explains the use of an analytical balance. In this video the instructor explains several key elements that are critical to making accurate measurements with the analytical balance. This includes making sure the balance pan is free of all debris and spills and measuring the object at room temperature. Objects that are above or below room temperature result in pressure changes leading to inaccurate results. While the video shows how to calculate the mass of the substance by noting the difference in mass with and without the substance on the measurement vessel, you can also obtain the mass of the substance directly by taring the empty measurement vessel.
