Chemistry
The fictitious compound, arrhenium fluoride ( ), reacts with itself to form a dimer with the formula Ah2F2 . The reaction is second order in AhF. The value of the rate constant is 8.591x10-3 M-1s-1. What is the initial rate of reaction in a reactor filled with AhF to a concent...

Chemistry
Oops, I mean the molarity would decrease because moles base / larger quantity in L = a small # therefore decreased molarity. Correct?

Chemistry
Or if you didn't correct this error, the molarity of the base would be higher than it should be. Is that correct?

Chemistry
How will overshooting the end point of an acid-base titration by adding too much base to KHP affect the calculated molarity of the base? I would think you would need to add more KHP, then more base to bring it to the endpoint. So the molarity calculated should be the same. Is ...

You dissolve 20.0 gms of sucrose (sugar) in 200 mL of ethanol 20ºC (density of ethanol at 20ºC is 0.789 gm/ml). What is the mass % of the solute?

Chemistry
Concentrated aqueous ammonia contains 1.00 mol NH3 dissolved in 2.50 mol H2O. What is the mole fraction of NH3 in concentrated aqueous ammonia?

Chemistry
You dissolve 17.1 gms of sucrose (sugar) in 100 mL of ethanol 20ºC. What is the molarity (M)?
