Explain what the tare function dose on an electronic top-loading balance. A student used a triple-beam balance to determine the mass of a solid and reported the to be 19.234 g. Is this reported mass experimentally valid? A student recorded the mass of a two-component solid mixture, then separated the two components and determined their individual masses. The student found the mass of one of the components to be greater than the mass of the original mixture. Explain how such a result could occur. Explain why a piece of laboratory tissue or tongs should be used to handle a sample container to be weighed. When using a triple-beam balance, you don’t need to wait until the pointer stops moving. What indicates that the correct mass has been determined? When weighing by subtraction, what precautions need to be taken not to contaminate the sample? A. Measuring Liquid Volumes 31 & 32 (assignment four)
