Determine the molarity of a solution made by dissolving 8.36g of mgcl2 in water where the final volume of the solution is 500.0ml

Answer : The molarity of solution is, 0.878 mole/L

Solution : Given,

Mass of = 8.36 g

Volume of solution = 500 ml

Molar mass of = 95.2 g/mole

Molarity : It is defined as the number of moles of solute present in one liter of solution.

Formula used :

where,

w = mass of (solute)

M = molar mass of

= volume of solution in liter

Now put all the given values in this formula, we get the molarity of a solution.

Therefore, the molarity of solution is, 0.878 mole/L

c is the answer because when something is left after something evaporates that shows the chemical change.

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.
