Some fertilizer blends contain magnesium nitrate (mgno3). suppose that a chemist has 1.24 liters of a 2.13 m solution of magnesium nitrate. if the chemist dilutes the solution to 1.60 m, what is the volume of the new solution? express your answer to three significant figures. the volume of the new solution is blank liters.

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
