Well, it is $5.89 \times 10^{- 4} \cdot m o l \cdot L^{- 1}$ $5.89xx10^-4*mol*L^-1$ ...

Explanation:

And in fact if you input the number (longhand) into your calculator, the calculator will probably convert it automatically.

We can extend this, and provide a definition of $p H$ $pH$ : $p H = - {log}_{10} [H_{3} O^{+}] = - {log}_{10} (5.89 \times 10^{- 4}) = - (- 3.23) = 3.23$ $pH=-log_10[H_3O^+]=-log_10(5.89xx10^-4)=-(-3.23)=3.23$ .

And we know that in aqueous solution $p H + p O H = 14$ $pH+pOH=14$ . So what is $p O H$ $pOH$ , and $[H O^{-}]$ $[HO^-]$ here?
