we are given that the volume of the container=202 ml(milliliter). also the density of the liquid is given =0.685 grams over milliliter. we know that the mass or weight of the liquid is given by: weight=density×volume . weight=(0.685×202) grams. weight=138.37 grams. hence, the weight of liquid that exactly fills a 202.0 milliliter container is 138.37 grams.
