The formula is 71682928282
The formula is given by Molarity of mgso4 required for the titration * Volume of mgso4 for the titration = Molarity of mgso4 used to make the solution * Volume of mgso4 used to make the solution.
So we have 0.5 * Volume of mgso4 = 100 * 0.2
So Volume of mgso4 = (100 * 0.2)/ 0.5
Volume = 20/0.5 = 40ml = 40 * 10^(-3)
Answer:Chlorine
Explanation:The distribution of electrons in an atom is called as Electronic Configuration. Formula 2n2 helps in the determination of the maximum number of electrons present in an orbit, here n= orbit number. The formula helps in determination of arrangement of electrons and is known as “Bohr Bury Schemes.”
Explanation:
Sand and iron fillings have the same size of particles.
It would be difficult to use a mesh to separate them. Also, sometimes , the iron filing clings well to the surface of the sand particles.
The best way to separate them is to use a bar magnet. The magnetic properties of the iron fillings will get it attracted to the bar magnet leaving the sand particles behind.
