Food dyes have very high LD50 values and they are consumed in very small quantities. Consider the solution that you worked with above that had an absorbance of 0.724 (from Determining Unknown Concentration Part I) at 710 nm. If this solution was a sports drink containing the dye and the dye has an LD50 of 3000 mg/kg, how many 240 mL (8 oz) servings of the sports drink would be required to reach the LD50 for the dye for a 61 kg individual

To find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? a) when more work was done, the couch was moved the same distance. b) when more work was done, the couch was moved less. c) when more work was done, the couch was moved further. d) when more work was done, the couch wasn't moved at all.
