Describe how to use the “difference method” when performing mass determinations. Why are masses in the chemistry laboratory usually determined by the difference method (using a beaker to contain the object to be weighted, rather than just placing the object directly on the pan of the balance)?
Required Materials A balance with at worst 0.1 g precision. This can be a laboratory or kitchen balance. Containers to […]
