  3. The kidneys of an average size adult female filter 110 mL of blood per minute. If Deirdre has 5.5 liters of blood, how many minutes will it take to filter all of her blood in one cycle? Clearly show your answer and calculation by completing the following dimensional outline. Avogadro's Number C7H6O3MW = 138.12 grams (Salicylic Acid) Atoms grams (Aspirin) Molecules Weight SA) Stoichiometry 5.5 L (Blood) ? minutes "Gatekeeper" grams (WO3) (Molecular (Molecular mol SA grams (SA) 1 mol (SA) Weight A) 1 mol (WO3) C9H8O4 MW = 180.15 ? mol A

  4. WO3(s) + 3 H2(g) → W(s) + 3 H2O(g) An experiment reacted 25.0 grams of WO3 (molar mass = 232 g/mol) with 0.35 moles of hydrogen and produced 18.0 grams of tungsten, what is the theoretical yield and the percent yield? grams (Aspirin) grams (Salicylic Acid) Avogadro's Number Atoms C7H6O3MW = 138.12 Molecules Stoichiometry grams (SA) (Molecular 25.0 grams (WO3) 1 mol (WO3) mol SA Weight SA) ?
