Answer:
Mass of lead, m = 687 g
Explanation:
The expression for the calculation of the enthalpy change of a process is shown below as:-
Where,
is the enthalpy change
m is the mass
C is the specific heat capacity
is the temperature change
Thus, given that:-
Mass = ?
Specific heat = 0.0380 cal/g°C
Heat added = 47.0 calories
So,
Mass of lead, m = 687 g
