Question

what would by the molarity of sodium hydroxide if we dissolve 40 grams of it in 1 litre of solution​

Answer 1

Answer:

dissolve 40 grams of it in 1 litre of solution

Answer 2

Answer:

By definition, the molarity of a substance is the amount of mole(s) of it dissolved in water to form 1 L solution. Then, the molarity of NaOH would be : (40 g/L)/(40 g/mole) = 1 mole/L = 1 Molar or simply written as 1 M.
