Answer: see the last column in the final table of the explanation below.
Explanation:
1) Arrange the data to understand the question:
<span>Acid Molarity Moles of H⁺ released per liter
HCl 1 ____
H2SO4 1 ____
H3PO4 1 ____
H2SO4 0.5 ____
H3PO4 3 ____
HNO3 2 ____
</span><span>
2) All the given acids are strong acids, so you can consider they dissociate completely and release all the hydrogens present in the chemical formula.
3) The molarity formula is M = n/V, where n is the number of moles of solute and V is the volume of the solution in liters
From that, n = M×V
Go one by one with that formula.

HCl 1 1M×1L = 1 1 1×1 = 1
H₂SO4₄ 1 1M×1L = 1 2 2×1 = 2
H₃PO₄ 1 1M×1L = 1 3 3×1 = 3
H₂SO₄ 0.5 0.5M×1L = 0.5 2 2×0.5 = 1
H₃PO₄ 3 3M×1L = 3 3 3×3 = 9
HNO₃ 2 2M×1L = 2 2 2×2 = 4

Explanation:
It is necessary that the glassware which we use during titration needs to be clean and dry before use because otherwise the remaining reagents will get mixed up with the solutions.
As a result, this will lead to a change in analysis results.
Hence, an error will occur in the resulting values.
Also, when not cleaned properly the any other substance remaining in the glassware might react with the solution leading to a change in the solution.
In that case also, error will occur.
