Answer:
Ring is made up off copper.
Explanation:
Given data:
Mass of ring = 89.2 g
Volume of water = 10 mL
Volume of water + ring = 20 mL
Ring is made up of = ?
Solution:
Volume of ring = (Volume of water + ring) - Volume of water
Volume of ring = 20 mL - 10 mL
Volume of ring = 10 mL
Density:
Density = mass/volume ( 1 mL = 1 cm³)
d = 89.2 g/ 10cm³
d = 8.92 g/cm³
Thus, ring is made up off copper.
