Answer:
3.72
Explanation:
Given data:
Mass of object = 82.2 g
Volume of water = 25.0 mL
Volume of water + object = 47.1 mL
Density of object = ?
Solution:
Volume of object:
Volume of object = (Volume of water + object) - Volume of water
Volume of object = 47.1 mL - 25.0 mL
Volume of object = 22.1 mL
Density of object:
d = 82.2 g/ 22.1 mL
d = 3.72 g/mL
