Question- A food chemist determines the concentration ofacetic acid in a sample of apple cider vinegar. the density of the sample was 1.01g/ml. the volume of 1.215 MNaOH required to titrate 25.00ml sample of vinegar was 19.85ml. What is the molar concentration and the percent yield by mass of acidic acid in this vinegar
