Explanation:
Molarity of sodium hydroxide = number of moles of sodium hydroxide / volume in liters
equation of reaction between NaOH and Potassium hydrogen phthalate
NaOH(aq) + KHC₈H₄O₄(aq) KNaC₈H₄O₄(aq) + H₂O(aq)
molar mass of KHC₈H₄O₄ = 204.22g/mol
amount required to titrate with NaOH = 0.5816 g
mole of KHC₈H₄O₄ = 0.5816 g / 204.22g/mol = 0.00285 mole
considering the equation, 1 mole of NaOH required 1 mole of KHC₈H₄O₄
0.00285 mole KHC₈H₄O₄ will require 0.00285 mole of NaOH
Molarity = 0.00285 mole / ( 23.73 ml / 1000ml) L = 0.12 M
Well, while we change in age, out sleep habits change too.
For instance, when we used to be in our teen age, we used to wake up late. Or, Now that were adults around our 20's we tend to wake up very early. Age tends to change out sleep of ways. Its always good to get at least 7 hours of sleep.
Hoped I answered you question. :)
The memory phenomena Gina is experiencing is Proactive interference. <span>This happens when old information hampers the recall of newer information. An example would be, when trying to recall a new phone number, the old phone number keeps popping up in your mind, to the point when it is very difficult to remember the new number.</span>
