A
4.68 x 10^-4
B
1.23 x 10^-3
C
3.67 x 10^-3
D
2.14 x 10^-4
Verified step by step guidance1
Understand that pOH is the negative logarithm of the hydroxide ion concentration. The formula to find the concentration of hydroxide ions from pOH is: \( [OH^-] = 10^{-\text{pOH}} \).
Substitute the given pOH value into the formula: \( [OH^-] = 10^{-3.67} \).
Use a calculator to compute the power of 10 raised to the negative pOH value. This will give you the concentration of hydroxide ions in moles per liter (M).
Ensure that your calculator is set to the correct mode (scientific) to handle the exponentiation correctly.
Verify your result by checking if it matches one of the provided options, ensuring that the calculation was performed accurately.
