3.An industry is required to clean up 2.50 m3 of a by- product containing both toxic and inert material (specific gravity = 1.6).The toxic content is 15% (by mass); the rest is inert.The by-product is treated with 55 t (metric tons) of solvent resulting in an amount of dirty solvent containing 0.35% toxic material (by mass) and a discard containing 1.2% toxic material (by mass),some solvent,and all the inert materials.
a) Determine the amount (in t) of the by-product.
b) Determine the amount (in t) and composition (in %) of the discard.
c) Determine the amount (in t) of the dirty solvent produced.
d) Determine the percentage of toxic substance (from the by-product) remaining in the dirty solvent.
