Qgain = -Qlost

Qgain = water

Qlost = aluminium

now, get heat equations

Qwater = mwater*Cwater*(Tf-Twater)

Qmetal = mmetal * Cmetal ( Tf-Tmetal)

now; substitute

mwater*Cwater*(Tf-Twater) = – mmetal * Cmetal ( Tf-Tmetal)

substitute known data

75*4.184*(28.3-24.9) = -mmetal * 0.9 * (28.3-81.9)

solve for mmetal

1,066.92 = 48.24*mmetal

m metal = 1,066.92/ 48.24

m metal = 22.1169 g of aluminium was used
