We establish uniqueness of finite volume approximate solution to scalar conservation laws with a non Lipschitz flux function in the whole space. Our arguments are based on properties of moduli of continuity of the components of the numerical flux.123120241231202496296999https://wseas.com/journals/mathematics/2024/b985106-2069.pdf10.37394/23206.2024.23.99https://wseas.com/journals/mathematics/2024/b985106-2069.pdf10.4208/aamm.2016.m-s1K.H.
