Solution A contained 40 cm3 volume of wine diluted to 100 cm3 using deionized water. Solution B contained 1 cm3 taken from Solution A and diluted to 10 cm3 with deionised water. After running Solution B through the GC it was found it contained 0.045 cm3 of ethanol. What is the % alcohol by volume (ABV) in the original wine sample?

When air (21 mol% O2, 79 mol% N2) is placed in contact with 1000 cm3 of liquid water at body temperature, 37°C, and 1 atm absolute, approximately 14.1 standard cubic centimeters [cm3(STP)] of gas are absorbed in the water at equilibrium. Subsequent analysis of the liquid reveals that 33.4 mol% of the dissolved gas is oxygen and the balance is oxygen a) Estimate the Henry’s law coefficients (atm/mole fraction) of oxygen and nitrogen at 37°C b) An adult absorbs approximately...

Calculate the volume of 0.20 mol/L KH2PO4 and the volume of 0.10 mol/L NaOH required to prepare 50.0 mL of buffer with a formal (or total) concentration of H2PO4 of 0.020 mol/L and a pH = 6.3. Repeat this calculation for buffers (of the same volume and formal concentration) with pH = 6.5, 6.9, 7.5, 7.9, and 8.2.

Problem 12: Several ice cubes (ρi = 0.9167 g/cm3) of total volume Vi = 275 cm3 and temperature 273.15 K (0.000 °C) are put into a thermos containing Vt = 610 cm3 of tea at a temperature of 313.15 K, completely filling the thermos. The lid is then put on the thermos to close it. Assume that the density and the specific heat of the tea is the same as it is for fresh water (ρw = 1.00 g/cm3, c...

A sample of unknown acid is dissolved into 100-mL of water (assume negligible volume change) and divided into two equal volumes. One flask, labeled as flask “a”, is titrated with 15.00ml to end point with 0.20 M NaOH. The second flask, labeled as flask “b”, is not titrated. Which of the following is false? a)Flask “a” contains some conjugate base of the acid before titration b) The concentration of A- in the titrated flask “a” is equal to the concentration...
