Ammonia has the formula NH3. Household ammonia is a dilute aqueous solution of NH3 . Aqueous ammonia is a base that can neutralize acids.

If 18.4mL of 0.800 M HCl solution are needed to neutralize 5.00 mL of a household ammonia solution, what is the molar concentration of the ammonia?

  4. Do you think you know how to figure out this one:
    Sorry about that

    The chemical 5-amino-2,3-dihydro-1,4-phthalazinedione, better known as luminol, is used by forensic scientists in analyzing crime scenes for the presence of washed-away blood. Luminol is so sensitive that it can detect blood that has been diluted 10,000 times. A basic solution of luminol is often sprayed onto surfaces that are suspected of containing minute amounts of blood.

    Luminol has a molecular weight of 177g/mol

    The forensic technician at a crime scene has just prepared a luminol stock solution by adding 14.0 of luminol into a total volume of 75.0 mL of H2O.

    1. What is the molarity of the stock solution of luminol?
    ANSWER:molarity of luminol solution =1.05 M

    2.Before investigating the scene, the technician must dilute the luminol solution to a concentration of 6.00×10−2 . The diluted solution is then placed in a spray bottle for application on the desired surfaces.

    How many moles of luminol are present in 2.00 L of the diluted spray?
    ANSWER: moles of luminol =0.120

    3.What volume of the stock solution (Part A) would contain the number of moles present in the diluted solution (Part B)?

    Answer: needs to be in mL and i cant figure it out. Can someone please help
