Answer:
0.93g/mL
Explanation:
Given parameters
Mass of wood = 3.16g
Initial volume of water = 20mL
Volume of water + wood = 23.4mL
Unknown:
Density of the wood = ?
Solution:
Density is the mass per volume of a substance.
It is mathematically expressed as;
Density = 
Volume of wood = 23.4mL - 20mL = 3.4mL
So,
Density = 
= 0.93g/mL
It would be Water and salts
