1. Calculate the molarity of a solution if 18 mol of CaCl2 is dissolved to make 200mL of solution.

The molarity is 90 M

Explanation:

Molarity is a measure of concentration that indicates the amount of moles of solute (in this case CaCl2) in 1 liter of solution (1000ml). In this case we calculate it that way:

200 ml solution 18 mol CaCl2

1000ml solutionx= (1000ml solutionx18 mol CaCl2)/200 ml solution

x=90 mol CaCl2---> the solution is 90 M

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.
