Kenneth's science class is learning about ways to find the volume of irregularly-shaped objects. For his first experiment, Kenneth finds that a small marble statue weighs 1.3 kilograms. Then, he uses its density to find its volume in liters. If the density of marble is approximately 2.6 grams per milliliter, what is the volume of Kenneth's statue? Write your answer as a whole number, decimal, or simplified fraction. Do not round.
