The imаge belоw shоws the micrоstructure of а leаd-tin (Pb-Sn) alloy resulting from slow equilibrium cooling. The dark circular regions are from the proeutectic (or primary) lead-rich phase, and the light-dark lamellar structure is from the Pb-Sn eutectic. Given that the weight fraction of the proeutectic phase is 0.27, use the lever rule to calculate the composition (C0) of the Pb-Sn alloy. Write your answer and show your work on the Final Exam Template.
