If 20.0 mL of .45 M NaOH are needed to neutralize 25.0 mL of HNO, what is the molarity of the HNO?

Question

australopithecus · Answer

1. Write out chemical reaction
2. Balance Chemical reaction
3. determine moles of NaOH using formula (you need to convert mL to L)
Molarity = moles/litres
4. Use moles of NaOH to determine moles of HNO that were consumed completely (divide by the number in front of NaOH and multiply by the number in front of HNO)
5. Use the molarity formula again to find concentration of HNO (you need to convert mL to L)
