9) A pure sample of an element was vaporized and injected into a mass spectrometer and the data was plotted on the graph belovr. The mass values for the isotopes were
found to be: A-56 (55.935 amu), A-54 (53.940 amu), A-57 (56.935 amu), and A-58
(57.933 amu). Find the average atomic mass and identify the element.

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m

The answer is a. mars

  you would need a flashlight, escape plans, canned foods, blankets, phone, car, money, clothes, and some more things that you think would be to get you out of the disaster safe and soundhope.  this : )
