Question

what is the concentration(in %) of a mixture obtained when 5 litres of 30% HCL solution is added with 2 litres of 40% of HCL solution and 4 litres of 25 % HCL?

Answer 1

Answer:

How to calculate HCl concentration (in molar) given Assay(35-38%) value?

On the bottle its written that Assay = (35-38%), also weight per ml = (~1.18g). now I need to have 9 M HCl of this HCl with this information, its not written on the bottle the exact concentration in M! so how to convert Assay to Molarity?
