Answer:
0.12 M
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
Explanation:
From the given parameters we can calculate the mass and number of moles in this amount of solution of NaCl
Volume of solution = 1L
Molarity = 0.5M
We know that this is a solution. The molarity indicates that amount of solute was dissolved in a solvent.
To find the number of moles of solution;
Number of moles = molarity x volume
molarity is the the number of moles of solute in a solution.
input the variables;
Number of moles = 0.5 x 1 = 0.5moles
Mass of NaCl:
Mass of NaCl = number of moles x molar mass
molar mass of NaCl = 58.54g/mol
Mass of NaCl = 0.5 x 58.54 = 29.27g

no it is not possible, because they both have the same number of valence electrons in each element. in a compound you are supposed to have two or more elements that have different numbers of valence electrons so when put together they for a compound.
They would be neutral if their electonegativity difference was 0
