Fe(NO3)3 is dissolved in enough water to make exactly 323 ml of solution, what is the molar concentration g

0.0659M

Explanation:

...5,15g  of Fe(NO₃)₃ is dissolved...

Molar concentration is the amount of moles presents in 1L of solution. To solve this question we need to find the moles of iron nitrate, Fe(NO₃)₃ present in the 323mL of solution:

Moles Fe(NO₃)₃ -Molar mass 241.86g/mol-:

5.15g Fe(NO₃)₃ * (1mol / 241.86g) = 0.0213moles Fe(NO₃)₃

And molarity is:

0.0213moles Fe(NO₃)₃ / 0.323L = 0.0659M

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
