Abstract
We compute the V-monoid of a weighted Leavitt path algebra of a rowfinite weighted graph, correcting a wrong computation of the V-monoid that exists in the literature. Further we show that the description of K0 of a weighted Leavitt path algebra that exists in the literature is correct (although the computation was based on a wrong V-monoid description).
