Ascientist is examining a mixture of nitrogen, hydrogen, and ammonia. the individual pressures that are exerted by nitrogen
and hydrogen are 0.26 atm and 0.28 atm, respectively. if the total pressure is 0.90 atm, what is the partial pressure of
ammonia?
use p7= pa + p2+p3++p
o 0.27 atm
o 0.36 atm
o 0.54 atm
o 0.90 atm

Calculate the ratio of h+ ions to oh– ions at a ph = 6. 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 = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
