A. Vinegar which is just a dilute acetic solution, is very common and versatile. The concentration of store-bought vinegar around a 5% solution by mass and is density is approximately 1.01 G/ml
B. Suppose I dilute does vinegar into a bottle 23 pours water plus one part vinegar in other words I make a solution that is 25% as strong as it was. Determine the molarity of the new vinegar solution.
C. How many Adams are carbon are in the 2 cups of this new vinegar you made in part a please show all work
A person ate 0.451 pound of cheese (an energy intake of 3610 kJ). Suppose that none of the energy was stored in his body. What mass (in grams) of water would he need to perspire in order to maintain his original temperature? (It takes 44.0 kJ to v..
