Concentration of solution is 20%
Mass of solute( common salt) is 80g
take the amount of water as x
mass of the solvent = (80+x)
We know, concentration of solution = (mass of solute/mass of solution)×100
20=(80/80+x)×100
80+x=80×5 ( we devide the both side by 20)
x= 400-80
x=320 g
An isotope is the vary of neutrons in an element, causing its atomic mass to change. While an ion is a charged atom that bonds to be stable.
The arrangement in space and the interatomic distances and angles of the atoms in crystals, usually determined by x-ray diffraction measurements
I know it would be calcium chloride, not sure why. Maybe someone could answer that part.
