A solution of MgSO 4 containing 43 g of solid per 100 g of water is fed

Question:

A solution of MgSO⁴ containing 43 g of solid per 100 g of water is fed to a vacuum crystallizer at 220°F. The vacuum in the crystallizer corresponds to an H₂O boiling temperature of 43°F, and a saturated solution of MgSO₄ has a boiling-point elevation of 2°F. How much solution must be fed to the crystallizer to produce 900 kg of epsom salt (MgSO₄ 7H₂O) per hour?
