I can't solve this problem. Could anyone help me?(adsbygoogle = window.adsbygoogle || []).push({});

A piece of metal with a mass of 2kg and specific heat of 200J/kg C is initially at a temperature of 120 C. The metal is placed into an insulated container that contains a liquid of mass 4kg, a specific heat of 600J/kg C, and an initial temperature of 20C.

I am using equation

Mm * Cm(Tf-Ti)=Ml*Cl(Tf-Ti)

2*200*(Tf-120)=4*600*(Tf-20)

(Tf-120)=6*(Tf-20)

Tf-120 = 6Tf-120

Tf=6Tf

Where did I make a mistake?

Thanks
