Antimony (Sb) has two stable isotopes. 121Sb has a mass of 120.90 amu. 123Sb has a mass of 122.90 amu. Answer the following questions on a separate
piece of paper and upload the document.
a. Write an equation to describe the relationship between the percent
abundance of 121Sb and the percent abundance of 123Sb. Assume that no
other isotopes exist.

b. Write an equation that you can use to calculate the percent abundance of
each isotope.
c. What is antimony's atomic mass? Use the periodic table.
d. Calculate the percent abundance for each isotope of antimony.

Nconcentration refers to the molar concentration of an ion in solution. it may be identical to, or greater or less than, the molar concentration of the compound containing the ion that was used to make the solution. for soluble salts, the molarity of a particular ion is equal to the molarity of that compound times the subscript for that ion. for example, 1 m of alcl3 is 1 m in al3+ and 3 m in cl−. 1 m of (nh4)2so4 is 2 m in nh4+ and 1 m in so42−. part a what is the concentration of k+ in 0.15 m of k2s? view available hint(s) nothing m m part b if cacl2 is dissolved in water, what can be said about the concentration of the ca2+ ion? view available hint(s) if is dissolved in water, what can be said about the concentration of the ion? it has the same concentration as the cl− ion. its concentration is half that of the cl− ion. its concentration is twice that of the cl− ion. its concentration is one-third that of the cl− ion. part c a scientist wants to make a solution of tribasic sodium phosphate, na3po4, for a laboratory experiment. how many grams of na3po4 will be needed to produce 550 ml of a solution that has a concentration of na+ ions of 0.700 m ? express your answer numerically in grams. view available hint(s) mass of na3po4 n a 3 p o 4 = nothing g provide feedback
