Glass Beads
Density of glass in form of very small beads using density bottle?

Mass of bottle empty = 26.5 g
Mass when partly filled with beads = 61.5 g
Mass of bottle + glass beads topped up with water =97 g
Mass when bottle is filled with water only =76 g

A) what is volume of glass bottle?
B)What is volume of glass beads?
C) What is density of glass beads?

1. Volume of glass bottle:
76 - 26.5 = 49.5 g water in bottle. Density of water = 1, so volume of bottle is 49.5 cm³.
Mass of beads = 61.5 - 26.5 = 35g
Mass water added to fill bottle = 97 -61.5 = 35.5g
Volume of water added = 35.5cm³
2. Volume of beads = 49.5-35.5 = 14cm³
3. Density of beads = 35/14 = 2.5g/cm³
