What is the Molecular mass of sodiumcholoride ?

58.5g/mol

Explanation:

Given substance:

 Sodium chloride  = NaCl

Unknown:

Molecular mass = ?

Solution:

The molecular mass of a compound is the gram-formula mass or gram-molecular weight of the compound.

It is determined by adding its component atomic masses and then express in grams per mole;

Atomic mass of Na = 23g

Atomic mass of Cl = 35.5g

 NaCl  = 23 + 35.5  = 58.5g/mol

its first and third is your answer i did the qustion the fourth isnt right

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.
