Julli [10]

Answer:

Theoretical density values

brass- $8.4-8.73 gm/cm^3$

bronze- $8.73 g/cm^3$

steel- $7.75 - 8.05 gm/cm^3$

Explanation:

All of these substances are alloys (a substance made from melting two or more substances, one of them usually being a metal). Brass is a combination of copper and zinc, bronze is mostly copper, tin and other non-metals as well and steel is majorly made up of iron and copper. These alloys have various uses and varying importance in different kinds of industries.
