Answer:
She has to mix 0.0550 moles of NaOH in a 550 mL solution to make a 0.100 M solution
Explanation:
Step 1: Data given
Concentration of the solution = 0.100 M
Number of moles NaOH = 0.0550 moles
Step 2: Calculate the volume of solution she needs
Concentration NaOH solution = number of moles NaOH / volume solution
Volume of the solution = Number of moles NaOH / Concentration NaOH solution
Volume of the solution = 0.0550 moles NaOH / 0.100 mol /L
Volume of the solution needed = 0.55 L
Volume of the solution needed = 550 mL
She has to mix 0.0550 moles of NaOH in a 550 mL solution to make a 0.100 M solution
