Explanation / Answer

Solution:

A) 183 deg cels since as one heats from 150 it reaches 183 to create the first liquid.

B) the corresponding liquid phase composition is 61.9

C)when heating is continuously done then the complete melting occurs at 232 deg cels.

D) the composition of last solid is 15 wt percent of Sn.
