Answer to Question #310059 in Organic Chemistry for Kay

Question

How many grams of Sodium hydroxide would you need to make 1L of  a 2M solution ?

Answer 1

We are making 1L of a 2M solution and for that how many grams of sodium hydroxide we need , for that

We know that , 1M = 1mol /L and for this solution we have 1mol of sodium hydroxide in it.

And

Sodium hydroxide has molar mass of 40g/mol,so we would need in total

2mol . $\frac{40g}{mol}$ = 80g of NaOH.
