You prepare a solution by dissolving 5.23 grams of Iron (II) nitrate in enough water to
make 256.0 cm3 of solution. What is the concentration of the solution?

I keep getting 0.05 M but it says it's wrong. Can anyone explain how to do it?

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
