Question

3. Dilute solutions of Silver Nitrate (100.0 millimolar) were used for newborns historically. Added to the eyes it is an antibacterial that protects newborrn eyes from infection and blindness. A nurse is preparing a new solution in the maternity ward, if they mix 1.7g silver nitrate into 500.0mL solution how close to the proper dilution is the nurse? (What was the concentration the nurse made?) Tin(I) fluoride is used to strengthen teeth through topical application.

If a dental application of topical foam is 5.0mL and contains 500nmol tin(II) fluoride and has a 5.0% yield of reaction how m

Explanation / Answer

3.

moles of AgNO3 in solution = 1.7 g x 1000/169.87 g/mol x 0.5 L

                                             = 20.01 mmolar

This is lot less concentrated than the actual solution used for newborns (100 mmolar).

molarity = moles/L of solution

moles = grams/molar mass
