How many moles of nacl are in 1 l of a 0.5 m solution?

Molarity= moles of solute/Liters of solution

1.55 M=moles.5 moles = 0.775 moles of NaCl

Explanation:

Molarity=moles of solute Liters of solution

First, we need to convert  500 mL to Liters 500 ml⋅1 L 1000 m=.5 L

Now we can plug into our formula 1.55M=moles .5 moles = 0.775 moles of NaCl

Hope it was helpful!

BRAINLIEST PLEASE!!!

i can ! i just need to know what the paragraph is! : p

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
