Question- What volume of oxygen gas is produced at 8C and 0.950atm from 21.8kg of carbon dioxide and an excess of water via the overall photosynthetic reaction 6CO2 + 6H2O = C6H12O6 + 6O2?
Show all work, use additional paper if necessary.
1.90-g sample of a large biomolecule was dissolved in 23.0 g of carbon tetrachloride. The boiling point of this solution was determined to be 77.85°C. Calculate the molar mass of the biomolecule.
If 28 mL of NaCl reacts completely with 46 mL of 0.44 AgNO3, what is the molarity of the NaCl solution? The reaction is: AgNO3 + NaCl = AgCl + NaNO3

Although acetic acid - water may be utilized as a "solvent pair", why are dilute solutions of an inorganic acid/water (or, inorganic base/water) avoided in recrystallization attempts
1) Suggest a reason why the starting material (trans-1,4-diphenyl-2-butene-1,4-dione) should be recrystallized prior to use in the photochemical isomerization of an alkene.
