If air bubbles were trapped in your solid beneath the liquid level in your density determination, what error would result in the
Alina [70]

error would result in the volume measurement too small.

The weighted volume would weigh less without the air bubbles because they are lighter than the material they have replaced.

Due to the fact that d = m/v and that if m is low, then d will also be low, this would result in a low side inaccuracy in the density.

<h3>What distinguishes the two concepts of volume and mass density?</h3>

Mass Density vs. Volume. Air pockets form between the granules when you use a graduated cylinder to measure the volume of a solid, such as salt that is granulated. This decreases the measurement's precision. When air bubbles are trapped inside a solid, they take up space, which reduces the solid's density and somewhat inflates the volume measurement.

<h3>How do air bubbles impact a solid's density?</h3>

When air bubbles are trapped inside a solid, they take up space, which reduces the solid's density and somewhat inflates the volume measurement. Compact the solid using the end of a small pestle, rubber "policeman," or stirring rod to lessen the effects of air bubbles in solids.
