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.
