Suppose you are measuring the mass of a solid sample on a balance using a weigh boat. You record the data in a table. Mass of weigh boat 3.451 g Mass of weigh boat and sample 7.268 g What is the mass of the solid sample (in g)?
Are students allowed to place a hot crucible on the balance? (Choose all correct answers) Yes. Hot objects do not harm the balance. No. Weighing hot objects will result in an incorrect mass. No. Weighing hot objects could damage the balance pan, balance, or both. Yes. Hot objects on the balance have no effect on the mass.
