How to find molarity 1.mass 2. molar mass 3. volume of water added?

Molarity = (numer of mole solute) / (volume of the solution)

number of mole solute = mass solute/molar mass solute

Molarity =( mass solute/molar mass solute)/ (volume of the solution)=

= ( mass solute/((molar mass solute)*(volume of the solution))

If m is a mass of the solute, M is a molar mass a solute, V is a volume of the solution (we can think as a volume of water added).

Molarity = m/(M*V)

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

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.
