What is the molarity of NaOH solution if 30.0g of NaOH solid was dissolved in 500.ml of water? (molar mass of NaOH is 40.0 g/mol
vivado [14]

Answer:

The answer to your question is:  1.5 M

Explanation:

Data

MW NaOH = 40 g/mol

mass = 30 g

V = 500 ml

Molarity (M) = ?

number of moles = n

Formula

M = n/V(l)

Process

                        40 g      -------------------  1 mol

                        30 g      ---------------------   x

                        x = (30)(1)/40

                       x = 0.75 mol

Volume

                     1000 ml -----------------  1 l

                       500 ml ----------------   x

                        x = (500)(1) / 1000

                        x = 0.5 l

Molarity = 0.75 / 0.5

             = 1.5 M
