If I change the volume of a solution from 5.00 L to 10.0 L, what was the new
concentration if the original concentration was 4.0 M? Please help me as soon as possible with explanation.

The new  concentration = 2 M

Further explanation

Dilution is a process of decreasing the concentration of a solution by adding a number of solvents

Can be formulated

M₁V₁=M₂V₂

M₁ = Initial Molarity

V₁ = Initial volume

M₂ = Final Molarity (after dilution)

V₂ = Final volume (after dilution)

V₁=5 L

V₂=10 L

M₁=4 M

The new  concentration(M₂) :

[tex]\tt M_2=\dfrac{V_1.M_1}{V_2}\\\\M_2=\dfrac{5\times 4}{10}\\\\M_2=2~M[/tex]
