Question

Determine the approximate density of a high-leaded brass that has a composition of 64.5 wt% Cu, 33.5 wt% Zn and 2.0 wt% Pb. The densities of Cu, Zn, and Pb are 8.94.7.13 and 11.35 g/cm,respectively. g/cm3 e Textbook and Media

Answer 1

Answer:

The approximate density of a high-leaded brass is δ = 8,40 g/mL

Explanation:

Lead brasses are used for their high machinability and atmospheric corrosion resistance. To obtain the density of this solid solution you need to do the weighted average, thus:

δ = $\frac{(64,5*8,97g/mL)+(33,5*7,13g/mL)+(2,0*11,35g/mL)}{100}$

δ = 8,40 g/mL
