Question

One liter of a NaOH solution contains 100 grams of NaOH. What

is the molarity of this solution?

Answer 1

2.5 molar.

Step-by-step explanation:

1 molar NaOH contains 40 grams ( adding up the atomic masses) per litre.

So a solution containing 100 grams has molarity 100 / 40

= 2.5 moles per litre.

Answer 2

Answer 100g/l

Step-by-step explanation:

mass/capacity

100/1
