Answer

2.146 g

Work Step by Step

It is given that a dioxin-contaminated water source contains 0.085% dioxin by mass. That means, 100 g of water contains 0.085 g of dioxin. The density of the solution is 1.01 g/mL. 2.5 L = 2500 mL = 2500 X 1.01 g = 2525 g For 100 of water → 0.085 g For 2525 g → ? = (0.085 X 2525)/(100) = 2.146 g
