Ernest Shackleton's South! primarily uses the writing structure of "problem and solution".
The answer is 18.23432 grams.
Molar mass of KOH= 56.1056

= 18.234 grams
Answer:
It's false
Explanation:
Mixtures are always combinations of the same compounds that are at different states.
Answer:
6.46 × 10⁻¹¹ M
Explanation:
Step 1: Given data
pH of the solution: 3.81
Step 2: Calculate the pOH of the solution
We will use the following expression.
pH + pOH = 14.00
pOH = 14.00 - pH = 14.00 - 3.81 = 10.19
Step 3: Calculate the concentration of OH⁻ ions
We will use the definition of pOH.
pOH = -log [OH⁻]
[OH⁻] = antilog -pOH = antilog -10.19 = 6.46 × 10⁻¹¹ M
