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 = $\frac{mass}{volume}$

Volume of wood = 23.4mL - 20mL = 3.4mL

So,

Density = $\frac{3.16}{3.4}$ = 0.93g/mL
