What is the molar concentration of 2.0 mol of KCl dissolved in 1000 mL of solution?

Explanation:

molar concentration = No.of moles of solute ÷ volume of solution (in litres)

= 2.0 × ( 1000 × 0.001 )

= 2

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
