Question

4. (5) Assume that you have a sample of vinegar which has been made in the lab (this contains acetic acid which is CHscool). If you have a standard solution of 0.103M NaoH solution, briefly describe how to determine the acetic content in the vinegar sample. Also, calculate the concentration of acetic acid if a 20.0mL sample of vinegar took 342ml of base to reach a phenolphthalein endpoint. Give the concentration as both molarity and by weight. pressure of 3.7 atm ifthe temperature is 25eC. 6 (0) 4.1 g of sodium fluoride is mixed with 100ml. (00g) of water, assume that 102ml of solution is obtained. Calculate the concentration of this solution using the following concentration units: (a) Molarity (b) Weight (m/m)
