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
The empirical formula of a group of compounds is CHCl. Lindane, a powerful insecticide, is a member of this group. The molar mass of lindane is 290.8. How many atoms of carbon does a molecule of lindane contain
A sample of gas has an initial volume of 13.8L at a pressure of 1.26 atm If the sample is compressed to a volume of 10.8L, what will its pressure be?
Choose the selection which correctly identifies the forces which must be overcome to convert NH3 from a liquid to a gas. a) Only London dispersion forces must be overcome. b) Only dipole-dipole forces must be overcome
In one of the neutron-induced fission reactions of U-235(atomic mass = 235.043922 ), the products are Ba -140 and Kr-93 (a radioactive gas). What volume of Kr-93(at and 1.0 ) is produced when 1.80 g of U-235 undergoes this fission reaction
(a) What is the pH of the solution when 75.0 mL of 0.100 M NaOH has been added to 100.0 mL 0.100 M acetic acid? (b) What is the pH at the equivalence point? (c) What is the pH after 110.0 mL of NaOH has been added?
