Question 21 pts

In Vinegar Analysis lab, at the end point of a titration, there is still a drop of NaOH solution hanging on the tip of burrette. How does this affect the experimental result in this lab?

Question 41 ptsSkip to question text.

At constant pressure, density of gas is inversely proportional to its temperature. This is how hot air balloon is floating in air: burning fuel makes inside air temperature higher and density lower; low density air balloon float on high density regular air. What is the density of air in g/L at 76 degree C if the atmospheric pressure is 1.0 atm? The average molar mass of air is about 29 g/mol. Keep two decimal places for your answer.

Explanation / Answer

beaker contains = vinegar, or acetic aicd

burette contains = NaOH, or base

we need 1 mol of base per mol of acid

a) is false, it does affect, since we wrote a volume containing this amount, will affect in the MV = mol equation

b) false, it must be higher

c) true, since we have a false volume, will affect the number of moles in solution
