Final answer:
To prepare a 6.0 M NaOH solution in 250 mL, you will need 60 grams of NaOH.
Step-by-step explanation:
To calculate the amount of NaOH needed to prepare a 6.0 M solution, we can use the formula:
Molarity (M) = moles of solute / liters of solution
First, let's calculate the moles of NaOH needed:
moles of NaOH = Molarity x liters of solution
Given: Molarity = 6.0 M, Volume of solution = 250 mL = 0.25 L
moles of NaOH = 6.0 M x 0.25 L = 1.5 moles
Next, let's calculate the grams of NaOH needed:
Grams of NaOH = moles of NaOH x molar mass of NaOH
The molar mass of NaOH is 40.00 g/mol.
Grams of NaOH = 1.5 moles x 40.00 g/mol = 60 grams
Therefore, option d) 54 grams is incorrect. The correct answer is option e) 60 grams.
