Explanation:
Answer:
0.07789 M is the sodium hydroxide concentration.
Explanation:
Mass of potassium hydrogen phthalate = 0.6986 g
Molar mass of potassium hydrogen phthalate = 204.22 g/mol
Moles of potassium hydrogen phthalate = 
According to reaction , 1 mole og KHp reactswith 1 mole of NaOH , then 0.003421 moles of KHp will react with :
Moles of NaOH = 0.003421 mole
Volume of NaOH solution = 43.92 ml = 0.04392 L ( 1 mL = 0.001L)
Concentration of NaOH :
0.07789 M is the sodium hydroxide concentration.
Answer:
The atomic mass of Potassium is 39.09 u+-0.0001u and molar mass is 39.09 g,s/mole
Explanation:
Potassium is a metal belongs to group 1 and period 4 whose atomic number is 19 and electron configuration is 2,8,8,1.
The molar mass of Potassium or K is 39.09 g,s/mole and the atomic mass is 39.09 u+-0.0001u. Potassium was first discovered by Humphrey Davey and was first found in the ashes of plants. It also occurs in the mineral sylvite or KCL and is mined as such.
