Answer:
The formula to calculate the change in energy (Q) for a temperature change is:
Q = m * c * ΔT
Where:
Q is the energy in joules (350,000 J in your case).
m is the mass of the material (what you're trying to find).
c is the specific heat capacity of the material.
ΔT is the change in temperature (in this case, from 50°C to 200°C, which is a 150°C change).
Without the specific heat capacity (c) of the material, it's not possible to calculate the mass (m) of the sample accurately. You need to know the specific heat capacity of the material to proceed with the calculation. If you have that information, please provide it, and I can help you calculate the mass.
