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)?
Sketch the [1-11] direction within the (110) plane relative to an fcc unit cell. Include all atom-center positions within the plane of interest.
If I want the molar mass of guanidine carbonate should I treat the reactants Guanidine and carbonate separate in which there is information for
Draw the two chairs (chair 1 and chair 2) conformers of trans-1-methyl-3-isopropylcyclohexane and indicate which one is the most stable. Draw the Newman projection of the most stable conformation
To extract Al from glass, 100 mL of edta were mixed with .50 g of glass particles and allowed to equilibrate over time. If the glass contained .80 wt% Al and .35% of Al was extracted by the EDTA, what was the Al concentration of equilibrated EDTA ..

What is the H+ concentration of an aqueous solution with a pOH= 4.38 at 25 degrees celcius.
Formic acid, HCOOH, the simplest carboxylic acid, is used in the textile and rubber industries and is secreted as a defense by many species of ants (family Formicidae). Calculate the percent dissociation of 0.38 M HCOOH.
Calculate the concentration of all species in a 0.100 M phosphorous acid solution. These species include {H3O}, {H2PO3} and {HPO3^2-}. For phosphorous acid, ka1=3.0*10^-2 and Ka2=1.7*10^-7
Question- In a nitration of phenol which will yield p-nitrophenol and o-nitrophenol, why doesn't meta nitration occur for phenols?
You are designing a drier that must evaporate 200 lb/h of H2O from sludge by using air. Air at 70°F and 50% relative humidity is drawn into the drier and it leaves at 140F and 70% relative humidity. How much volume of dry air needs to be used for ..
