We have the volume and the concentration of sulfuric acid, and we can find the number of moles of sulfuric acid, using the following formula:
[tex]M=\frac{n}{V}\begin{cases}M=\text{concentration} \\ n=\text{moles} \\ V=\text{volume}\end{cases},[/tex]We clear the number of moles and replace the given data:
[tex]n=M\cdot V=7.50\cdot25000L=187500\text{ moles.}[/tex]Remember that a cubic meter equals 1000 liters.
Using the molar mass of sulfuric acid, we can obtain its
