Sagot :
300.0 ml of 0.10 m CaCl₂ of the following solutions contains the greatest number of ions, assuming all these salts dissociate completely.
What are ions simple definition?
An is an atom or collection of atoms where the number of electrons and the number of protons are different. A positive ion, also known as a cation, is a particle that exists when the flow of atoms exceeds the number of protons. Ions are electrically charged particles that are created either by taking electrons out of neutral atoms to make positive ions or adding protons to neutral atoms to produce negative ions. The quantity of protons remains constant during the formation of an ion.
Briefing:
The number of moles in 300. mL of 0.10 M CaCl₂ is:
0.300 L * 0.10 Mol L = 0.030 mol
Each mole of CaCl₂ contains 3 moles of ions (1 Ca²⁺ and 2 Cl⁻). The moles of ions in 0.030 moles of CaCl₂ are:
0.30molNaCl * 3mol Ions / 1 mol NaCl = 0.90 mols
