Hi guys, I have run in this problem.
Calculate the ph of the solution obtained by mixing 50g of potassium nitrate with 1l of H2O.
Ka = 7,1 * 10^-4
I don't understand if it is a buffer solution or if ir isn't solvable.
Thank you for the replies.

Re: Stoichiometry problem
The calculation for oxygen is wrong, because the molecule also contain oxygen. The masses of CO2 and H2O correspond to C and H. Calculate the moles of it and do a ratio to unbroken numbers. The mass of silverchloride correspond to the mass of Chlorine. Do also mole ratio. If you have C, H and Cl su...

Stoichiometry problem
Hi guys, I have this problem: An organic compound, which contains C, H, O and Cl gave the following results: 0.16g produce from combustion 0.265g of CO2 and 0.0325g of H2O. If I melt 0.215g of the compound in water with the addiction of AgNO3 I obtain 0.236g of AgCl. Find the molecular formula of th...
