Souring of wine occurs when ethanol is converted to acetic acid by oxygen: C2H5OH(l) +O2(g)--->CH3COOH(g)+H2O(l). A 1.00 L bottle of wine labeled as 7.00% (%v/v) ethanol, is found to have a defective seal. Analysis of 1.00 mL showed that there were 0.0274 g acetic acid in that 1.00 mL. The density of ethanol is 0.816 g/mL. (a) What mass of oxygen must leaked into the bottle in pounds(lb) (b) What is the percent yield for the conversion of ethanol to acetic acid, if oxygen is in excess

What is the concentration of a 62.0 % (w/w) concentrated nitric acid (HNO3, Mr = 63.0 g/mol) solution (density: 1.32 g/cm3) in mol/dm3 (molarity) and g/dm3 (mass concentraion) units? How many cm3 do you need to dilute into 200.0 cm3 from that concentrated nitric acid if you would like to have a solution with a concentration of 3.0 mol/dm3 ?
At elevated temperature NaHCO3 is quantitatively converted to Na2CO3. By calcining 0.3592 g of an antacid tablet containing NaHCO3, 0.2362 g of Na2CO3 was obtained.
