What is the normality of a solution that contains 1.89g of h2c2o2 2h2oin of solution?

First convert mass to number of moles. Molar mass of H2C2O2 • 2H2O = 94 / mol

1.89g / (94 g / mol) = .02 mol H2C2O2 • 2H2O

Then we divide by 0.1 L, or 100 mL, and we get a concentration of 0.2 M.

Since there are two positive ions (2 H+), therefore normality is:

0.4 N

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.
