A) At what temperature does the first liquid phase form?
B) What is the composition, tin weight by %, of this liquid phase in part A?
C) What concentration of tin necessary to have 60% alpha 40% liquid at 260°C?

I don't understand what B part ask..
This is my answer, A) 183°C , C) 17.6%
Thank You:smile_40:
