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 !!

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;

is initial concentration

is initial volume

is final concentration of the solution

is final volume of the solution

Therefore, the H+ (aq) concentration of the resulting solution is 4.1 mol/dm³

it's c. elements are placed in rows based on how may valencies electrons have.

there is none because earth is stationary and flat.
