Approximately .
Explanation:
<h3>Number of moles of formula units of magnesium sulfate required to make the solution</h3>The unit of concentration in this question is "". That's equivalent to "
" (moles per liter.) In other words:
.
However, the unit of the volume of this solution is in milliliters. Convert that unit to liters:
.
Calculate the number of moles of formula units required to make this solution:
.
Look up the relative atomic mass data of ,
, and
on a modern periodic table:
:
.
:
.
:
.
Calculate the formula mass of using these values:
.
Using this formula mass, calculate the mass of that (approximately) of
formula units:
.
Therefore, the mass of required to make this solution would be approximately
.
