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)

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    

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
