Question: "To prepare a fertilizer solution, a florist dilutes 1.0 L of 0.20 m NH4NO3(aq) by adding 3.0 L of water. The florist then adds 100. mL of the diluted solution to each plant. How many moles of nitrogen atoms will each plant receive? Solve this exercise without using a calculator."

The solutions manual used 3.0 L of water as their final volume, but if the florist is "adding" 3.0 L of water to the initial volume which was "1.0 L of water", shouldn't the final volume be 4.0 L of water and not 3.0 L of water?

You're right, it should be 4 L of water as the final volume! Did you check to see if the final answer is correct? Maybe it was a typo, or they really did solve it incorrectly. The answer should be 1.0 x 10^-2 mol of N!
