What is the total number of moles of NaCl(s) needed to make 3.0 liters of a 2.0 M NaCl solution? *

6 moles of NaCl are needed to make 3.0 liters of a 2.0 M NaCl solution.

Explanation:

A 2M solution means that there are 2 moles of solute (NaCl in this case) in 1 liter of solution:

1 L solution2 moles of NaCl

3 L solutionx= (3 L solutionx2 moles of NaCl)/1 L solution= 6 moles of NaCl

14,16 18 reacts with group

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.
