Question

a solution is made by diluting 15.00 ml of a 0.2971 M sucrose solution to a total volume of 100.00 ml. What is the molarity of sucrose in the new solution?

Answer 1

0.044 56 mol·L⁻¹

Step-by-step explanation:

We can use the dilution formula:

c₁V₁ = c₂V₂ Divide each side by V₂

c₂ = c₁ × (V₁/V₂)

c₁ = 0.2971 mol·L⁻¹; V₁ = 15.00 mL

V₂ = 100.00 mL

c₂ = 0.2971 × 15.00/100.00

c₂ = 0.2971 × 0.150 00

c₂ = 0.044 56 mol·L⁻¹
