Calculate the absorbance of a $25\mathrm{.}00mM$ solution of a compound $"C"$ that has the molar absorptivity coefficient of $36\mathrm{.}50M-1Cm-1,$ if the cell path is $0\mathrm{.}500cm$

a$.1\mathrm{.}1000$

b$.0\mathrm{.}5475$

c$.0\mathrm{.}456$

d$.0\mathrm{.}750$

e$.0\mathrm{.}950$

Calculate the concentration of a solution preparing it in the following way: $8\mathrm{.}0mL$ of $HCl37\mathrm{.}0\%(\frac{w}{w})$ and it is brought to $1\mathrm{.}0L$ of the solution with distilled water.

NOTE: density of $HCl37\mathrm{.}0(\frac{w}{w})\%$ is $1\mathrm{.}19\frac{g}{m}L$

a$.0\mathrm{.}12M$

b$.0\mathrm{.}052M$

c$.,0\mathrm{.}097M$

d$.0\mathrm{.}063M$

e$.0\mathrm{.}081M$

Solution $"$A$"$ has a concentration of $2mM.$

Solution $"$B$"$ has a concentration of $1M,$ what is the dilution factor to prepare $B$ from $A?$
