Latrice is given an unknown substance and is asked to identify is based on his properties. She measures its mass as 239.6grams. The cubes length, width and height are 3 cm. What is the unknown substance

density = 8.87g/cm³

From chart the density shows that it is a Colsibro copper alloy, a precipitation hardening copper nickel silicon.

Step-by-step explanation:

This problem bothers on the density of substances

Given data

Mass m of substance = 239.6grams

length l=3cm

width b=3cm

height h=3cm

Volume of substance = l*b*h

=3*3*3=27cm³

We know that the density of the substance ρ=mass/volume

ρ = 239.6/27 = 8.87g/cm³
