Answer 1

The answer is attach below

given data vinegar : percent acchic acid on label, 2.5 mass of 25 ml of vinegarg 24.56 Baking soda : formula de porcent NaHCO3 4100%. mass of baking soda (9 . final volume of Vinegar in ML.) 1.27 21 mL 1.50 2.00 30mL 2.58 36mL Cup 23mL Vinegar density, I 0.9824 density mass volume = 24.56g 20.9824 25mL 98249/mL

Graph between baking soda versus vinegar (36,2.58) NaHCO3(g) +2.39 +2.23 +2.07 (38;2.00) +1.91 +1.75 +1.59 3341.50) +1.43 1.43 V12732.5 24 26.5 27 28.5 30 31.5 33 34.5 Vinegar (ML)

- 1 From graph , slope of best straight line drawn data points on your gruph, g Nalle 83 mL vinegar 235/1.50me grams of foot 13 C-count per milliliter of vinegar, g - sl of 0.98299 0 → Eliner 0.98240 4men = 0.049 19459.
