To determine the concentration of the H2SO4 solution, we need to use the equation:
c1v1 = c2v2
Where:
c1 = concentration of H2SO4
v1 = volume of H2SO4 used
c2 = concentration of NaOH
v2 = volume of NaOH used
We know that the concentration of NaOH is 1.00 M, and the volume of NaOH used is 18 mL. The volume of H2SO4 used is 25 mL, and we want to find the concentration of H2SO4.
So the equation becomes:
c1 * 25 mL = 1.00 M * 18 mL
To solve for c1, rearrange the equation:
c1 = (1.00 M * 18 mL) / 25 mL
c1 = 0.72 M
Therefore, the concentration of the 25 mL solution of H2SO4 is 0.72 M.
c1v1 = c2v2
Where:
c1 = concentration of H2SO4
v1 = volume of H2SO4 used
c2 = concentration of NaOH
v2 = volume of NaOH used
We know that the concentration of NaOH is 1.00 M, and the volume of NaOH used is 18 mL. The volume of H2SO4 used is 25 mL, and we want to find the concentration of H2SO4.
So the equation becomes:
c1 * 25 mL = 1.00 M * 18 mL
To solve for c1, rearrange the equation:
c1 = (1.00 M * 18 mL) / 25 mL
c1 = 0.72 M
Therefore, the concentration of the 25 mL solution of H2SO4 is 0.72 M.
