Chemistry
HA and HB are two strong monobasic acids. 25.0cm3 of 6.0mol/dm3 HA is mixed with 45.0cm3 of 3.0mol/dm3 HB.
What is the H+ (aq) concentration in mol/dm3 in the resulting solution ?
A 1.9
B 2.1
C 4.1
D 4.5
If anyone could explain how to reach an answer that would be so helpful !!

Ответ:
The H+ (aq) concentration of the resulting solution is 4.1 mol/dm³
(Option C)
Explanation:
Given;
concentration of HA,
= 6.0mol/dm³
volume of HA,
= 25.0cm³, = 0.025dm³
Concentration of HB,
= 3.0mol/dm³
volume of HB,
= 45.0cm³ = 0.045dm³
To determine the H+ (aq) concentration in mol/dm³ in the resulting solution, we apply concentration formula;
where;
Therefore, the H+ (aq) concentration of the resulting solution is 4.1 mol/dm³
