The concentration of glucose in the new solution will be

30 M mol/liter.

Subtract the solute's mass from the total volume of the solution. Using m as the solute's mass and V as the total volume of the solution, write out the equation C = m/V.

A concentrated solution is referred to as a stock solution since it will be diluted to a lesser concentration before usage. M₁V₁ = M₂V₂ is the dilution equation.

                     A diluted solution = stock solution.

M₁ is the stock solution's molarity.

M₂ stands for the diluted solution's molarity.

V1 is the volume of the starting solution.

V2 is the volume of the final solution.

M₁ = 90M mol/liter

V₁ = 20mL

V₂ = 40mL

Using the formula,

                               M₁V₁ = M₂V₂

                 20mL × 90 M mol/liter = 40mL × M₂

                              M₂ = 30 M mol/liter

Therefore, the concentration of glucose in the new solution will be

30 M mol/liter.
