pH = -log[H₃O⁺]

We can rearrange this formula to discover the concentration of H₃O⁺.  After rearranging the formula will look like this.

[H₃O⁺] = 10^-pH

When we are dealing with strong acids and their concentrations, this formula will alway be useful.

I hope this helps.

Concentration of (H3O+) = 10^-pH

(H3O+)= 10^-0.24

           = 0.5754

           = 0.58 mol/L

  IMPORTANT NOTES FOR THIS QUESTION

1. Remember to round your answer to the right amount of sig digs (2) 

2. The unit for concentration is mol/L

3. pH has no units
