Question

How many moles of h2so4 are needed to make 85 ml of .750 m solution?

Answer 1

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:

$molarity=\frac{moles}{volume, L}\\\\\therefore Moles=Volume, L\times Molarity\\\\\\=\frac{85}{1000}L\times 0.750\ mol/L\\\\=0.06375\ mol$

Hence, 0.06375 moles of sulfuric acid are needed.
