A sample of iron absorbs 81.0 J of heat, upon which the temperature of the sample increases from 17.9 °C to 32.5 °C.

Inessa [10]

Answer:

Mass = 12.33 g

Explanation:

The expression for the calculation of the enthalpy change of a process is shown below as:-

$\Delta H=m\times C\times \Delta T$

Where,

$\Delta H$ is the enthalpy change

m is the mass

C is the specific heat capacity

$\Delta T$ is the temperature change

Thus, given that:-

Specific heat = 0.450 J/g°C

$\Delta T=32.5-17.9\ ^0C=14.6\ ^0C$

$\Delta H$ = 81.0 J

So,

$81.0=m\times 0.450\times 14.6$
