10. What is the molarity of alcohol (C 2 H 6 O, density = 0.78g/mL) in an "80 proof" alcoholic beverage?

What is the molarity of alcohol (C2H6O, density = 0.78g/mL) in an "80 proof" alcoholic beverage? 100 proof is equivalent to 50 mLs alcohol in 100 mLs of solution. 

11. Fill in the following table for the substances below. For solubility, state whether it is soluble (S) or insoluble (I) in water. Under "electrolyte", state whether it is a strong (SE), weak (WE), on non-electrolyte (NE). Under acid/base/salt, state whether it is a strong or weak acid (SA or WA), a strong or weak base (SB or WB), salt, or neither

12. What is the molarity of a solution of HCl based on the following data. A few drops of an indicator were added to a 25 mL sample of the acid, which was titrated with 0.04M NaOH. The initial burette reading was 5.0 mLs. NaOH was added to the acid/indicator solution until the indicator changed color, which occurred when the final burette reading was 28.3 mLs. Molarity of acid = -------------
