A big irregular shaped vessel contained water, conductivity of which was 2.56 x 10^-3S^-1m^-1. 585 g of NaCl was then added to the water and conductivity after the addition of NaCl, was found to be 3.06 x 10^-3S^-1m^-1. The molar conductivity of NaCl at this concentration is 1.5 x 10^-2S^-1m²mol^-1. The capacity of vessel if it is fulfilled with water, is
