<span>Good Morning!
 
The entry and exit of substances from cells occurs through the plasma membrane. The control of external and internal water balance is performed through the osmosis process. In osmosis, water moves according to solute concentrations: always from the lowest concentration to the highest concentration.

In a titration experiment, a 10.00 ml sample of H2SO4 was titrated with 33.25 mL of 0.777 M KOH.
german

Answer:

1.292 M

Explanation:

<em>In order to calculate the concentration of H2SO4, we need to get the balanced equation of reaction first;</em>

H_2SO_4 + 2KOH --> K_2SO_4 + 2H_2O

Using the formula:

CaVa/CbVb = na/nb

where Ca = concentration of acid, Va = volume of acid, Cb = concentration of base, Vb = volume of base, na = number of moles of acid, and nb = number of moles of base.

In this case, Ca =?, Va = 10.00 ml, Cb = 0.777, Vb = 33.25 ml, na = 1, nb = 2

Ca = CbVbna/Vanb = 0.777 x 33.25 x 1/10 x 2

Ca = 1.292 M

Hence, the concentration of H2SO4 is 1.292 M
