When students added 2.0g NaI crystals to 100.ml of Pb(NO3)2(aq), a yellow peevipitae is formed. after the solution was filtered, the yellow solid was dried and weighed. data from the experiment are shown in the table above. which of the following claims is best supported by the observations

How many grams of co(g) are there in 74.5 ml of the gas at 0.933 atm and 30o c?

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
