Let R be a commutative ring with nonzero identity and U.R/ its multiplicative group of units. Let M be an R-module where the collection of prime submodules is non-empty and let N be an arbitrary union of prime submodules. Also, suppose that c 2 U.R/ such that c 1 D c. We define the extended total graph of M as a simple graph T c .M; N / with vertex set M , and two distinct elements x; y 2 M are adjacent if and only if x C cy 2 N. In this paper, we will study some graph theoretic results of T c .M; N /.
