Answer
Moles of NaOH = 0.250 moles
Explanation
To calculate the number of moles of sodium hydroxide (NaOH) in a given volume of solution, we use the formula:
In this question, we are given:- Molarity (M) of NaOH = 0.100 M (Molar)- Volume of NaOH solution = 2.50 LBy substituting these values into the formula, we can find the number of moles of NaOH.Moles of NaOH = 0.100 M × 2.50 L
