Determine the volume of concentrated hydrochloric acid required to prepare 10.0 L of a 0.200 mol/L solution

Question

anonymous · Answer

Please don't provide the answer , just explain what to do and why :)

aaronq · Answer

Use: $\sf M_1V_1=M_2V_2$

where M is molarity and V is volume

anonymous · Answer

so what your saying is, this is a dilution question?     and also they dont give you the concentration of HCl though.....      @aaronq

abhisar · Answer

Take the molarity of concentrated HCl as 12.1 M

anonymous · Answer

is that a you have to just know it thing? or didyo calculate to get it?

abhisar · Answer

NO, it is something to learn. Concentrated for some commonly used acids and bases is defined as, the maximum solubility (at room temperature) in an aqueous solution or as a pure liquid.

abhisar · Answer

Are you given with the answer?

abhisar · Answer

Is it clear?

anonymous · Answer

so i have to memorize it? sorry i have no idea

abhisar · Answer

Yes..it's better to memorize for some common reagents.

anonymous · Answer

so in the question tho above could i have calculated to get the concentration of HCl     and oh ok

abhisar · Answer

No, I don't think so. You will have to memorize the standard value of concentrated HCl

anonymous · Answer

oh ok so the site that you gave me, is it all common reagents?   i want to memorize some of them

abhisar · Answer

Yes, you don't need to memorize all of them.

anonymous · Answer

i know haha i said some, like ammonia and HCL but thanks!
