A student performs a gravimetric analysis experiment to determine the molar mass of an unknown alkali metal carbonate. During filtration, the filtrate was not clear but cloudy, due to the presence of precipitate that passed through the filter paper.

How will the student's calculated molar mass compare with the actual molar mass of the sample?

A

The molar mass will be too high.

B

The molar mass will be too low.

C

The molar mass will not be affected by the loss of the precipitate since it is not the unknown compound that was lost.

D

The molar mass will not be affected by the loss of the precipitate since the filtrate is discarded at the end of the experiment.
