SUMMARY
The speed of sound in an alloy composed of 91.67% gold (AU) and 8.33% copper (CU) can be approximated using the formula v = √(B/ρ), where B is the bulk modulus and ρ is the density of the mixture. The speed of sound in gold is established at 3240 m/s, while a consistent value for copper is not readily available. The speed of sound in this alloy will be primarily influenced by the gold content, necessitating the calculation of the alloy's density based on the weighted average of the constituent elements' densities.
