A melt containing 900 moles of anorthite and 100 moles ot diopside undergoes crystallization. The number of moles of anorthite that crystallizes as the melt composition moves from P to O is P 1553 1500 Melt 1400 Anorthite + Melt 1300 Diopside+ Melt 1274 1200 Diopside + Anorthite Di 20 40 50 60 80 90 An
Answer: 800 moles
Using lever rule;
Fraction of Anorthite crystallized as melt composition moves from P to Q is:
(90-50) / (100-50) = 40/50 = 0.8
Total number of moles in melt =...
