Answer:


\boxed{5.01* 10^(-9)\text{ mol/L}}

Step-by-step explanation:

pOH = 5.30

pH = 14.00 - 5.30 = 8.70

pH = -log[H₃O⁺]


\begin{array}{rcl}[\text{H}_(3)\text{O}^(+)] & = & 10^{- \text{pH}} \text{ mol/L}\\ & = & 10^(-8.30)\text{ mol/L}\\ & = &\boxed{\mathbf{5.01* 10^(-9)}\textbf{ mol/L}}\\\end{array}
