180.189 g was the mass of the zinc sample with a specific heat of zinc is 0.390 j/g°C.
<h3>What is specific heat capacity?</h3>The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C).
Using specific heat capacity formula here:

0.390J/g°C × ×77.4ºC = 4.184J/g°C× 65.0g × 20.00ºC.
= 180.189 g
Hence, 180.189 g was the mass of the zinc sample.
