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) :
![\tt M_2=(V_1.M_1)/(V_2)\\\\M_2=(5* 4)/(10)\\\\M_2=2~M](https://img.qammunity.org/2021/formulas/chemistry/college/23nepqcd205lquqjfmpg4kde1ut4fmishy.png)
