part 1 Which of the following is a best practice in weighing solid samples?   Use weighing paper, a watch glass, a beaker, or some other container to measure mass of your solid samples.   Do not return the mass settings to zero mark; let the next user tare it for you.   Place chemicals directly on the balance pan.   For different trials of an experiment, use multiple balances for your measurements

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
