A container full of mercury weighs 1000g. the empty container weighs 320 g. the density of the mercury is 13.6 g? cm3. what is the volume of the box?

Weighs of mercury & the weighs of the container is = 1000 g. The weighs of the container only is 320 g. Then, weighs of the mercury is = (1000 - 320) = 680 g. The density of the mercury inside the container is = 13.6 g Then, the volume of the box is = 680/13.6 = 50 g.
