4 0

Answer:

0.06375 mole

Explanation:

The following data were obtained from the question:

Volume = 85mL

Molarity of H2SO4 = 0.750 M

Mole of H2SO4 =..?

Next, we'll convert 85mL to a value in L.

This is illustrated below:

1000mL = 1L

Therefore, 85mL = 85/1000 = 0.085L

Now, we can obtain the number of mole of H2SO4 as follow:

Molarity is simply defined as the mole of solute per unit litre of the solution i.e

Molarity = mole /Volume

Mole = Molarity x Volume

Mole of H2SO4 = 0.750 x 0.085

Mole of H2SO4 = 0.06375 mole

Therefore 0.06375 mole of H2SO4 is needed to make the solution
