Problem- Household ammonia is a dilute solution of ammonia in water, usually around 3-5% by mass. A 13. mL sample of household ammonia was titrated by 34.90 mL of .110 M HCL. Calculate the molarity of the ammonia and the mass percent, assuming the solution has a density of 0.985 g/mL.
I just need a general explanation of it please- Thanks
Problem- Give the formula of each coordination compound. Include square brackets around the coordination complex. Do not include the oxidation state on the metal. Use parentheses only around polyatomic ligands. For ethylenediamine, use (en) in the..
