Answer:
d = 0.84 g/cm³
Explanation:
Given data:
Mass of wood = 2.85 g
Volume of water = 20.0 mL
Volume of water + wood = 23.4 mL
Density of wood = ?
Solution:
Volume of wood = (Volume of water + wood ) - Volume of water
Volume of wood = 23.4 mL - 20.0 mL
Volume of wood = 3.4 mL
1 mL = 1 cm³
Density of wood:
d = m/v
d = 2.85 g / 3.4cm³
d = 0.84 g/cm³
