To find the concentration of ( \text{H}_3\text{O}^+ ) in a solution with ( \text{OH}^- = 2 \times 10^{-8} , \text{M} ), we can use the water dissociation constant ( K_w = 1 \times 10^{-14} ) at 25°C. The relationship is given by ( [\text{H}_3\text{O}^+] = \frac{K_w}{[\text{OH}^-]} ). Substituting in the values, we find ( [\text{H}_3\text{O}^+] = \frac{1 \times 10^{-14}}{2 \times 10^{-8}} = 5 \times 10^{-7} , \text{M} ).

What is 5.8x10 to the power of minus 3 plus 1.6 x10 to the power of minus 6?
To add (5.8 \times 10^{-3}) and (1.6 \times 10^{-6}), we first convert (1.6 \times 10^{-6}) to the same exponent as the first term. This becomes (0.0000016), or in scientific notation, (0.0000016 = 0.0000058) when expressed with the same exponent. Therefore, (5.8 \times 10^{-3} + 0.0000016) is approximately (5.8000016 \times 10^{-3}), which can be written as (5.8 \times 10^{-3}) when rounded to three significant figures.
How much does a 2''x10''x10' fir board weigh?
A 2"x10"x10' fir board typically weighs around 35 to 40 pounds. The weight can vary slightly depending on the specific moisture content and density of the wood. For more accurate calculations, it's best to refer to local lumber weight charts or use a scale.
What is pH of aqueous solution that contain 3.98 X10-9M in hydronium ions?
The pH of a solution can be calculated using the formula pH = -log[H3O+]. Plugging in the concentration of hydronium ions given (3.98 x 10^-9 M) into the formula will give you the pH of the solution.
