You have a styrofoam container with $909$ g of milk $($specific heat of $3,930$ J$/($kg $$C$))$ at $35\mathrm{.}0$ and you add a $69$ g chunk of ice at $0$C$.$ Assume the liquid and water mix uniformly as the ice melts and determine the final temperature of the mixture $($in $$C$).$

$26\mathrm{.}42$C

$($b$)$

What If$?$ What is the minimum mass of the ice cube $($in g$)$ that will result in a final mixture at exactly $0$C$?$

$375$ g
