You need to make 200 mL of a 0.20 M aqueous solution of sodium chloride. The only available solution is 1.0 M. Determine how to make the needed dilution. answer choices

What is the gold assay

Sorry i dont understand the question can you rephase it?

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
