How many mL of a 4.0% NaOH solution do you need to have 16 g of NaOH?

Question

Quizplus · Accepted Answer

To find the volume of a 4.0% NaOH solution required to have 16 g of NaOH, we need to use the formula:

mass = volume x concentration x density

where mass = 16 g (given), concentration = 4.0% (given as percentage, which means 4.0 g NaOH in 100 mL solution), and density = 1.0 g/mL (given for water-based solutions).

Rearranging the formula, we get:

volume = mass / (concentration x density)

Substituting the values, we get:

volume = 16 g / (4.0 g/100 mL x 1.0 g/mL)
volume = 400 mL

Therefore, the answer is C, 400 mL.
