Answer:

Q = 319.49 J

Explanation:

Given that,

Mass, m = 16.6 g

Initial temperature, [tex]T_i=40.2^{\circ} C[/tex]

We need to find the heat needed to warm the water to 44.8 °C. The formula that is used to find the heat required is given by :

[tex]Q=mc\Delta T\\\\Q=mc(T_f-T_i)\\\\Q=16.6\ g\times 4.184\ J/g^{\circ} C\times (44.8-40.2)^{\circ} C\\\\Q=319.49\ J[/tex]

So, 319.49 J of heat is needed to warm water.
