Assume that you inherit a farm and now have to purchase fertilizer for the farm. The farm is 340 acres and also had corn planted the previous year. You must add fertilizer
to the soil before you plant this year's crop. You go to the local fertilizer store and find
SuperPhosphate TM brand fertilizer. You read the fertilizer bag and can recognize from your high
school chemistry class a molecular formula Ca, P H 3,021 (you don't understand anything else
written on the bag because it is imported fertilizer from Japan). You must decide how much
fertilizer to buy for application to your cornfields. If each bag costs $54.73; how many bags of
fertilizer do you need to purchase and how much will it cost you to add the necessary fertilizer to
your fields?

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
