V solution= 100ml = 0,1 l Molecular weight of H 2SO 4 is
m (H 2SO 4) = 4,904 г M (H 2SO 4) = 98 g /mol. Using the formula

Calculate ν = т / М

С m – ? let us calculate the amount of H 2SO 4 moles:

The molar concentration of 100 ml (0,1 L) sulfate acid solution is

calculated as follows:

Answer: С m = 0,5 mol/dm
3

Example 3. Calculate the molar concentration of 15% sulfate acid solution (ρ

3
= 1.10 g/cm ).

Input: Solution :

Ρ solution= 1,10 g/сm 3 The molar concentration of the solution

ω solution= 15 % is calculated by the formula:

Determine
С m (H 2SO 4) – ?

Knowing that ν = т s s./М, and
