Answer:Approximate density of the high-leaded brass(alloy) =8.306g/cm³
Step-by-step explanation:
The density of an alloy is its mass (100g) divided by its volume
Therefore we have that the alloy (high-leaded brass) has a composition of
60.5 wt% Cu with density 8.94g/cm3
34.5 wt% Zn, wth densty 7.13g/cm3
5.0 wt% Pb with densty g/cm3
The total volume of the alloy will be the mass / density of ts composition given as :
60.5gCu/DCu + 34.5gZn/DZn + 5.0gPb/Dpb
= 60.5/8.94 + 34.5/7.13+ 5.0/11.35
= 6.76 cm³ + 4.838 cm³+0.4405 cm³ = 12.0385cm³
Approximate density of the high-leaded brass(alloy) = 100g/ 12.0385cm³ =8.306g/cm³
