Determine the relative amounts (in terms of volume fractions) for a 15 wt% sn-85 wt% pb alloy at 100â°c. the densities of tin and lead at 100â°c are given as follows: ïsn = 7.29 g/cm3 ïpb = 11.27 g/cm3

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
