    1. The problem statement, all variables and given/known data

    A florist prepares a solution of nitrogen-phosphorus fertilizer by dissolving 5.95 g of NH4NO3 and 4.66 g of (NH4)3PO4 in enough water to make 23.0 L of solution. What are the molarities of NH4 and PO43- in the solution?

    2. Relevant equations

    3. The attempt at a solution

    Not sure what to do with this one, can someone help?

    Once again, you need to explain what you don't understand! What have you tried? You must be able to do at least part of this question, since you know how to convert between grams and moles.

    Do i need to convert the grams to mol, then divide the amount of mol (solute) by the volume (L) of solution
