A 25 mL sample is pipetted from a AB, stock solution. Which answer correctly describes the relationship of the moles of AB3 and the concentration of the solution of this sample vs the stock solution in the initial flask? a. There are fewer moles of AB3 in the pipetted sample. The concentration of the pipetted sample is lower than the original flask. b. There are more moles of AB3 in the pipetted sample. The concentration of the pipetted sample is the same as the original flask. c. There are fewer moles of AB3 in the pipetted sample. The concentration of the pipetted sample is the same as the original flask. d. There are the same moles of AB3 in the pipetted sample. The concentration of the pipetted sample is the same as the original flask. e. There are more moles of AB3 in the pipetted sample. The concentration of the pipetted sample is higher than the original flask.

Question

A 25 mL sample is pipetted from a AB3 stock solution. Which answer correctly describes the relationship
of the moles of AB, and the concentration of the solution of this sample vs the stock solution in the
initial flask?
a. There are fewer moles of AB3 in the pipetted sample. The concentration of the pipetted sample
is lower than the original flask.
b. There are more moles of AB3 in the pipetted sample. The concentration of the pipetted sample
is the same as the original flask.
c. There are fewer moles of AB3 in the pipetted sample. The concentration of the pipetted sample
is the same as the original flask.
d. There are the same moles of AB3 in the pipetted sample. The concentration of the pipetted
sample is the same as the original flask.
e.
There are more moles of AB3 in the pipetted sample. The concentration of the pipetted sample
is higher than the original flask.
