Measure 25cm³ of the ammonia provided and transfer it into a conical flask at 50cm³ of 0.1mol of sodium hydroxide to the ammonia in the conical flask add three drops of phenolphthalein filled the burette provided with 0.1mol of HCl solution and titrate it against the excess HCl in the conical flask. repeat the titration two or three times following the same procedure. calculate concentration of the ammonia in mol/dm³. Balance the equation for the reaction.​

Ineed to find the answer of this question because i dont understand it

What is the molar mass of potassium nitrate, kno3

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) and 3% carbon disulfide (cs2) is to be recovered from the bottom of a distillation column. the feed to the column is 16 mole% cs2 and 84% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.
