When making ice cream, the ingredients must be kept below 0.00 °C in an ice-salt bath. Assuming the salt dissolves completely, what mass, in g, of NagPO4 Would be needed to lower the melting point of 1.51 kg of ice to -4.12 °C? You may ignore ion pairing. MW of Na3PO4 = 163.94 g/mol K = 1.86 °C/m for water

When making ice cream, the ingredients must be kept below 0.00 °C in an ice-salt bath. Assuming the salt
dissolves completely, what mass, in g, of NazPO4 Would be needed to lower the melting point of 1.51 kg of
ice to -4.12 °C? You may ignore ion pairing.
MW of Na3PO4 = 163.94 g/mol
Kf = 1.86 °C/m for water
