...A dioxin-contaminated water source contains 0.044% dioxin by mass. How much dioxin is present in 6.5 L of this water? (Assume that the density of the solution is 1.00 g/mL.)

thanks

  2. 0.044% means 0.044 g/100 g soln or
    0.044 g/100 mL (Technically this is 0.044 g/(100-0.044) but for very dilute solutions we usually ignore that small difference.
    0.044 g/100 is how many g in 6.5L? That is
    0.044 g x 6,500 mL/100 mL = ??
