In order to find out the density of a small rock, eddie dropped the rock into a graduated cylinder fill with 52.5 ml of water. the level of the water went up to 68.1 ml. eddie then placed the rock on a triple beam balance, and its mass was 27.69 g. a. what is the volume of the rock? b. what is the density of the rock?

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
