Answer 2

Answer: see the last column in the final table of the explanation below.

Explanation:

1) Arrange the data to understand the question:

Acid                 Molarity         Moles of H⁺ released per liter

HCl                      1                  ____

H2SO4                1                   ____

H3PO4                1                   ____

H2SO4                 0.5               ____

H3PO4                 3                   ____

HNO3                   2                  ____

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.


Acid          Molarity    Moles of solute    number of H in            Moles H⁺                                  per liter                 the chemical formula  per liter

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
