Question

6.
Commerical available conc. HCL contains 38%.
HCL by mass.
a) What is the molarity of this solution. (density is
1.19g / cm 2)?
b) What volume of Conc. HCL is required to
make y L of o.10 M HCL ?​

Answer 1

Answer:

density of solution = 1.19 glml

Molarity =

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

12.389×v=1

v=
