Question

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

Answer 1

0.06375 moles

Step-by-step 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=(moles)/(volume, L)\\\\\therefore Moles=Volume, L* Molarity\\\\\\=(85)/(1000)L* 0.750\ mol/L\\\\=0.06375\ mol`

Hence, 0.06375 moles of sulfuric acid are needed.
