In the same class two students find that a piece of wood with a mass of 70g has a volume of 103 cm3 they conclude the wood is oa
k is this accurate

Answer:
The density of oak is ranging from 0.6 - 0.9 g/cm³ and the density of given wood is 0.68 g/cm³ . The piece of wood is oak.
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Given data:
Volume= 103 cm³
Mass = 70 g
Density = ?
Solution:
d = m/v
d = 70 g/ 103 cm³
d = 0.68 g/cm³
The density of oak is ranging from 0.6 - 0.9 g/cm³. so the piece of wood is oak.
