Answer:
0.06375 moles
Explanation:
Molarity is defined as moles of a solute per volume of solution.
-Given the molarity is 0.750m and the volume is 85ml
#Apply the molarity formula to solve for moles:
[tex]molarity=\frac{moles}{volume, L}\\\\\therefore Moles=Volume, L\times Molarity\\\\\\=\frac{85}{1000}L\times 0.750\ mol/L\\\\=0.06375\ mol[/tex]
Hence, 0.06375 moles of sulfuric acid are needed.
