Answer:
if
of
is dissolved completely in water to make a
solution.
Explanation:
Look up the relative atomic mass data on a modern periodic table:
:
.
:
.
:
.
Calculate the formula mass of :
.
Find the number of moles of formula units in that of
:
.
is a strong base. When dissolved in water, it ionizes completely to produce
ions and hydroxide ions (
.)
Note that there are one moles of ions in each mole of
formula units. When that
of
(approximately
of
formula units) dissolves completely in water to make a
solution, about
of
ions will be produced.
Convert the unit of volume to liters: .
Calculate the concentration of ions in that solution:
.
Calculate the of that solution:
.
