Please can someone help me with this question?

The freezing point depression constant for water is -1.86 "C/m. Atwhat temperature will a solution containing 7.99 g BaCl, and 52.0 gH,O begin to freeze? Assume that no ion-pairing occurs betweenBast and CI.O -4.12 'C0 -2.75 *C0 -1.37 'CO -0.857 C0 -0.248 *C
