Vinegar, which is just a dilute acetic acid solution, is very common and versatile. The concentration of store-bought vinegar around a 5.0 % solution by mass, and its density is approximately 1.01 g/mL. (a) Suppose I dilute this vinegar into a bottle to 3 parts water + 1 part vinegar (in other words, I make a solution that is 25% as strong as it was) . Determine the molarity of this new vinegar solution. (b) If I use 2 cups (473.2 mL) of this new vinegar solution from part (a) to help create a cleaning solution for my windows, how many molecules of acetic acid is this? (c) How many atoms of carbon are in 2 cups of this new vinegar you made in part (a)?
