Question

commercial available conentrated HCl contains 45% of HCl by mass i)What is the molarity of this solution , if the density of the solution is 1.19g/mol? ii)what is the volumeof con.HCl is required to make 1 L of 0.24M HCl ?

Answer 1

Answer:

density of solution = 1.19 glml

Molarity =

MolarmassofHCl

1.19

×1000×38%

=

36.5

1.19

×1000×

38

12.389m

mole of HCl required to make 10 L of all 0.1MHCl=10×0.1=1mole

12.389×v=1

v=

12.389
