can you help me mwith this write the correct significant figure and standard form

Calculate the value of OH from the given H3O+ in each solution and label the solution as acidic, basic, or neutral.

Note: The ion product of water = 1.0 x 10~14

Part 1 of 2

Be sure your answer has the correct number of significant figures.
[H30+]=10-5 M

[OH7]=

This solution is (Choose one)

[OH-]=1.0 x 10^(-9) M

This solution is acidic.
