What is the molarity of a solution containing 0.05 moles of solute in 0.25L of solution?

  0.2 M

Explanation:

The molarity is the number of moles per liter:

  (0.05 moles)/(0.25 liter) = 0.2 moles/liter = 0.2 M

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.
