q1 = mass ice x heat capacity ice x (Tf-Ti) where Tf is 0 and Ti = -14.

q2 = heat to melt ice

q2 = mass iced x heat fusion.

q3 = heat to raise T of melted ice from zero C to Tfinal.

q3 = mass melted H2O x specific heat H2O x (Tf - Ti) where Tf is the unknown and Ti = 0

q4 = heat released by warm water at 81.0C dropping to Tfinal.

q1 + q2 + q3 + q4 = 0.

Substitute and solve for Tf. Post you work if you get stuck.
