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

View answer and explanation

Correct option: C

\mathrm{C}{\mathrm{u}_4}\mathrm{A}{\mathrm{g}_3}\mathrm{Au}

Option C (

\mathrm{C}{\mathrm{u}_4}\mathrm{A}{\mathrm{g}_3}\mathrm{Au}

) is correct because the ratio of Cu, Ag, and Au atoms in the alloy is 4:3:1 based on their positions in the ccp lattice.
