![m_1\times c_1\times (T_{final}-T_1)=-[m_2\times c_2\times (T_{final}-T_2)]](/tpl/images/1150/2880/09236.png)
.................(1)
= mass of first sample of ethanol = 100 ml
= mass of second sample of ethanol = 300 ml
= final temperature = ?
= temperature of first sample of ethanol = 
= temperature of second sample of ethanol = 
= 
= specific heat of ethanol![-100\times (T_{final}-298)=[300\times (T_{final}-268)]](/tpl/images/1150/2880/2eae3.png)
