By titration, 24.9 mL of aqueous H2SO4 neutralized 20.5 mL of 0.0365 M LiOH solution. What was the molarity of the aqueous acid
solution?

Molarity = 0.014 M

Explanation:

Given data:

Volume of H₂SO₄ = 24.9 mL

Molarity of H₂SO₄ = ?

Volume of LiOH = 20.5 mL

Molarity of LiOH = 0.0365 M

Solution:

Volume of LiOH:

20.5 mL × 1 L /1000 mL

0.0205L

Volume of H₂SO₄:

24.9 mL × 1 L /1000 mL

0.0249 L

Chemical equation:

H₂SO₄ + 2LiOH        →     Li₂SO₄  +   2H₂O

Number of moles of LiOH:

Molarity = number of moles / volume in L

0.0365 M = number of moles /  0.0205L

n = 0.0365 M × 0.0205L

n = 0.0365 mol/L × 0.0205L

n = 0.0007 mol

now we will compare the moles of LiOH and H₂SO₄

               LiOH           :         H₂SO₄

                  2              :           1

              0.0007        :         1/2×0.0007 = 0.00035 mol

Molarity of H₂SO₄:

Molarity = number of moles / volume in L

Molarity = 0.00035 mol / 0.0249 L

Molarity = 0.014 M

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
