A solution of NaCl ( aq ) is added slowly to a solution of lead nitrate, Pb ( NO 3 ) 2 ( aq ) , until no further precipitation occurs. The precipitate is collected by filtration, dried, and weighed. A total of 19.58 g CaCl2 ( s ) is obtained from 200.0 mL of the original solution. Calculate the molarity of the Pb ( NO 3 ) 2 ( aq ) solution.

Answer : The molarity of  solution is, 0.352 M

Explanation :

First we have to calculate the moles of

Molar mass of = 278.1 g/mol

Now we have to calculate the moles of

The balanced chemical equation is:

From the balanced reaction we conclude that

As, 1 mole of produced from 1 mole of

So, 0.07041 mole of produced from 0.07041 mole of

Now we have to calculate the molarity of

Therefore, the molarity of  solution is, 0.352 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
