Answer:
a. Approximately
.
b. Approximately
.
Explanation:
The unit of concentration "
" is equivalent to "
", which means "moles per liter."
However, the volume of both solutions were given in mililiters
. Convert these volumes to liters:
.
.
In a solution of volume
where the concentration of a solute is
, there would be
(moles of) formula units of this solute.
Calculate the number of moles of
formula units in each of the two solutions:
Solution in a.:
.
Solution in b.:
.
What volume of that
(same as
)
solution would contain that many
For the solution in a.:
.
Convert the unit of that volume to milliliters:
.
Similarly, for the solution in b.:
.
Convert the unit of that volume to milliliters:
.
It will melt or the molecules inside of it will get hot
