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.
