What is the concentration of no3- ions in a solution prepared by dissolving 25.0 g of ca(no3)2 in enough water to produce 300. ml of solution?

1.016 M is the concentration of nitrate ions in a solution.

Explanation:

Molarity of the solution is the moles of compound in 1 Liter solutions.

Mass of calcium nitarte = 25.0 g

Molar mass of calcium nitrate = 164 g/mol

Volume of the solution = 300 mL = 0.3 L ( 1 mL =0.001 L)

According to reaction 1 mole of calcium nitrate gives 1 mole of calcium ion and 2 moles of nitrate ions.

1.016 M is the concentration of nitrate ions in a solution.

personal, she chose to do it.

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.
