Question

Using the table below, identify the unknown material that has a mass of 15,06 g and a

Answer 1

The unknown material : gold

Further explanation  

Density is a quantity derived from the mass and volume  

Density is the ratio of mass per unit volume  

Density formula:  

$\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}$

ρ = density  

m = mass  

v = volume  

mass of unknown the material : 15.06 g

volume = 0.78 ml

The density :

$\tt \rho=\dfrac{m}{V}\\\\\rho=\dfrac{15.06}{0.78}=19.31~g/ml$

materials that match the density: gold
