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%

Here it should refer to the pure liquid phase, which coincides with the eutectic point. You can read the composition corresponding to this point from the x-axis.
