The density of your hcl is 1.179. Mass of hcl in one molar solution which is the molar mass is 36.5. but the percentage purity of the hcl is 35% according to you. That means, 35% of that 36.5g is in 1 molar/dm3. Which means, your mass will be 35% of 36.5 =36.5*35/100 35.5*0.35=12.775 WebCalculate the pH at the equivalence point for the titration of 0.160 M methylamine (CH3NH2) with 0.160 M HCl.
