Respuesta :

The Molarity of volumetric flask 1 : 1.26 M

The Molarity of volumetric flask 2 : 0.06 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)

Volume of volumetric flask = 500 ml
