An alloy of copper, silver and gold is found to have copper constituting the ccp lattice. If silver atoms occupy the edge centres and gold is present at body centre, the alloy has a formula :

CuAgAu

`Cu_(4)Ag_(2)`Au

`Cu_(4)Ag_(3)Au`

`Cu_(4)Ag_(4)Au`

Text Solution

Verified by Experts

Number of Cu atoms at corners = `8xx(1)/(8)=1` , Number of Ag atoms at edge centres = `12xx(1)/(4)=3`
Number of Au atoms at body centre `= 1xx1=1 " " :.` Formula is Cu4Ag3Au.
