The only list containing molecules is list #4

NaCl, N2, and H2O are all made up of more than one element, making them molecules. The other lists contain an element. Mg, He, and Fe are elements, not molecules.

Hope this helps!

A student has 0.75 L of a 5.0 M solution and dilutes it to make 3.5 liters. What’s the molarity of the diluted solution?
Marianna [84]

The molarity of the diluted solution : 1.1 M

<h3>Further explanation</h3>

Dilution is the process of adding solvent to get a more dilute solution.

The moles(n) before and after dilution are the same.

Can be formulated :

\tt n_1=n_2\\\\M_1.V_1=M_2.V_2

M₁ = Molarity of the solution before dilution  

V₁ = volume of the solution before dilution  

M₂ = Molarity of the solution after dilution  

V₂ = Molarity volume of the solution after dilution

M₁=5

V₁=0.75

V₂=3.5

\tt M_2=\dfrac{M_1.V_1}{V_2}\\\\M_2=\dfrac{5\times 0.75}{3.5}\\\\M_2=1.07\approx 1.1
