A 1.60 g sample of a large biomolecule (a nonelectrolyte) was dissolved in 18.0 g of carbon tetrachloride. The boiling point of this solution was determined to be 77.85°C. Calculate the molar mass of the biomolecule. For carbon tetrachloride, the boiling point constant is 5.03°C·kg/mol, and the boiling point of pure carbon tetrachloride is 76.50°C.
Household vinegar is 5.0% acetic acid (CH3COOH). IF you have 240.0 mL of vinegar, how many molecules of CH3COOH would there be?
Determine the calculated pH of the solution if initially there is 2.0mL of CH3COOH at an initial concentration of 0.89M and 0.80mL of 1.0M Hydrochloric Acid is combined.
