Students in Dr. Lee's class were conducting solubility experiments using sucrose and water. Students began with room temperature
water (22oC) and then heated the water to boiling. They calculated the amount of sugar that could be dissolved in the water as the temperature increased. Marge and Bill lost their data and were trying to graph their results from memory. Help them out! Which graph is the MOST reasonable representation of their expected data? A) B) C) D)

<h3>Further explanation</h3>Reaction
2FePO₄ + 3Na₂SO₄ ⇒ Fe₂(SO₄)₃ + 2Na₃PO₄
mol FePO₄ (MW=150,82 g/mol) :
mol Fe₂(SO₄)₃ : mol FePO₄ = 1 : 2, so mol Fe₂(SO₄)₃ :
mass Fe₂(SO₄)₃ (MW=399,88 g/mol) :
