Question

How to prepare 10 percentage hcl solution in 100ml water?

Answer 1

as you know molecular weight of HCl=36.48g/mol

Density=1.16

So volume required for 1L=Mass/density=36.48/1.16=31.44 mL

Your weight percentage is 35%

So,for 1L of 1N/1M HCl, volume required=31.44/35%=89.85 mL

You want to prepare 100 mL

so you have to take 8.985mL of HCl from the conc. HCl and add water upto 100 mL
