An interplanetary probe returns to earth with soil samples. the atoms in the sample are sorted by their number of protons. a new element is discovered! the new element has 120 protons. 20.0% of these new atoms have 120 neutrons, and the remaining 80.0% have 110 neutrons. they decide to call the new element bolognium, bo. what average atomic mass should the scientists report in amu? enter your answer below to the nearest whole number with no units.

What is avogadro’s number, and why is it useful

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
