Question
Suppose a student measured the mass of a sample that has a known mass of 40.5809 g using an analytical balance. The mass they observed was unstable, constantly jumping between 39.5 and 41.5. Choose all of the following reasons that could cause this error. O The doors to the analytical balance were not closed completely, allowing an air current to circulate inside the balance. One weigh boat was used to tare the balance while a different one was used when the sample was massed. Twice the amount of sample was placed on the analytical balance. O The sample was heated, causing a convective flow.
