You can purchase nitric acid in a concentrated form that is 70.3% hno3 by mass and has a density of 1.41 g/ml. describe exactly how you would prepare 1.15 l of 0.100 m hno3 from the concentrated solution.

You will need to dilute 7.30 ml of the concentrated solution into the 1.15 L of the diuluted one by adding water.

Explanation:

First you need to calculate how much acid you'll need in order to prepare the diluted solution. If you know the volume and the molarity, just multiply.

1.15 l * 0.1 M = 0.115 mols of HNO3

Multiplying by the molar mass you'll convert that value into grams

0.115 * 63g/mol = 7.245 g HNO3

Now you use the concentrated solution to know how much to extract.

70.3 g of HNO3 pure are in 100 g of Solution, then 7.245 are in x

X= (7.245 * 100)/ 70.3 = 10.3 grams of concentrated solution.

Using the density you convert the mass into volume:

V = m/dens --> V = 10.3 g / 1.41 g/ml --> V= 7.3 ml

You'll take 7,30 ml of the concentrated solution and add water until reach the required volume for the solution.

the answer is: they rebelled against saddam hussein’s rule.

kurds opposed saddam rule and wanted independence. kurds in the north and shiites in the south revolt against hussein.

for example, the halabja attack in 1988 conducted against the kurdish people by the iraqi regime under saddam hussein, where between 4000 people are killed and around 9000 are injured.
