The density of the glass can be determined using the formula:
- Density of the glass = (Mf - Mi)/20 cm³
<h3>What is density?</h3>
Density is defined as the ratio of mass and volume of a substance.
The mass of the glass = Final mass of beaker - initial mass of beaker (Mf - Mi)
The initial mass of the beaker is not given.
Volume of the glass marble = 20 cm³
Density of the glass = (Mf - Mi)/20 cm³
Therefore, the density of the glass is determined from the ratio of the mass and volume of the glass.
