imeisya29 makasih

mendokusai $T_c = \frac{m_1*T_1 + m_2*T_2}{m_1 + m_2}$
$T_c = \frac{1*90 + 2*60}{1 + 2}$
$T_c = \frac{90 + 120}{3}$
$T_c = \frac{210}{3} = 70^oC$
--------------------------------------------------------------------------------
$Q = m*c*(T_2 - T_1)$
$Q = 100*0,11*(75 - 25)$
$Q = 11*50$
$Q = 550 kalori$

Semoga membantu :)
