Answer:
2.857 × 10⁻⁴ M
Explanation:
First, we will calculate the molarity of the solution 1.
M = mass of solute / molar mass of solute × liters of solution
M = 0.5028 g / 879.9 g/mol × 0.100 L
M = 5.714 × 10⁻³ M
We can find the concentration of the final solution using the dilution rule.
C₁ × V₁ = C₂ × V₂
C₂ = C₁ × V₁ / V₂
C₂ = 5.714 × 10⁻³ M × 5 mL / 100 mL
C₂ = 2.857 × 10⁻⁴ M
