My crystal ball isn't working well today. You don't have nearly enough information to answer a question. You need volume NaOH. Use this mL HCl x M HCl = mL NaOH x M NaOH and solve for the M HCl. Post your work if you get stuck.

Chemistry
First the M of HCl must be determined from the titration with NaOH. NaOH + HCl ==> NaCl + H2O Since the molar ratio or the reactants is 1:1, one may use mL x M = mL x M. Use that to determine M HCl. Then go to the Ca(OH)2 solution. 2HCl + Ba(OH)2 ==> BaCl2 + 2H2O Here ...

I"m not a biochemist so all of this substrate business is not my cup of tea; however, my educated guess is to do this. (I think C1 is 10 mM PNPP.) 10*V1 = 3.5*1 mL V1 = 0.35 mL. Then buffer + 0.4 mL enzyme = 0.2 mL Total so far is 0.95 mL, then add water to make a total of 1 ...

M 37% HCl is 1.19 g/mL x 1000 mL x 0.37/36.46 = 12.08M M 10g/L is 10/36.46 = 0.274 M Then use the dilution formula of c1v1=c2v2. My answers is 2.268 which rounds to 2.28 mL. I suspect the only difference is in what we used for the molar mass HCl

CHemistry- For Dr.Bob
I found your question of last Tuesday, July 31. You wanted mass HCl soln. That is 1.05 x 5.00 mL = 5.25 g mass HCl in the 5.00 mL. That = mols HCl (which you obtained from M x L) x molar mass HCl = grams HCl. Then mass H2O = 5.25 - grams HCl = mass H2O.
