Plzz me to find the concentration
3.92 g of h2so4 is dissolved in distilled water of 200cm^3. find the concentration of h2so4.
if 5ocm^3 of this solution is taken out and distilled watef is added to it until it reaches 400cm^3..find the concentration of h2so4 in it

Concentration of the first solution: approximately 0.200 mol/L.

Concentration of the diluted solution: approximately 0.0250 mol/L.

Explanation:

Refer to a modern periodic table for relative atomic mass data:

Formula mass of sulfuric acid :

.

Number of moles of in of this substance:

.

Convert cubic centimeters to liters:

.

.

.

Concentration of this solution:

.

While both the volume and the concentration of the solution changes when it is diluted, the number of moles of in this solution will stay the same. Number of moles of in this of concentrated solution:

.

That will be the same as the number of moles of in the diluted solution.

Concentration of this solution after it is diluted to :

.
