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
