What effect would an incomplete decomposition of KCLO3 have on an experimentally determined molar mass? Explain using the ideal gas law
ideal gas law is
PV = nRT
n = PV / RT
n = number of moles of O2
decomposition reaction is
2 KClO3 .............> 2 KCl + 3 O2
During incomplete decomposition, number of moles of O2 obtained is less.
Hence
moles of KClO3 theoretically less than expected.
we know,
moles = mass / molar mass
or
molar mass = mass / moles.
as moles of KClO3 is less and hence experimentally determined molar mass should be decrease or less than expected.

In a lab where molar volume of H2 gas is determined, it is important to allow the reaction to equilibrate for two minutes once it is complete. If you did not allow this to happen, what effect would it have on the calculated standard molar volume? Be specific—i.e. would you expect the calculated standard molar volume to be higher or lower than if you had waited?
During the calculations for titration of vinegar experiment, you determined the molar mass of KHP by using the mass of K, H, and P instead of using KHC8H4O4. How would this change your results? Explain. We had to find the mass of KHP, moles of KHP, moles of NaOh, and moles of acetic acid, molarity of vinegar titrated, mass of acetic acid titrated in grams, and w/v % of acetic acid in vinegar
