an iron calorimeter has a heat capacity of 68.85 kJ/oC. what is its mass

To determine the mass of the iron calorimeter, we need to follow these steps:

Step 1: Understand the concept

The heat capacity formula is given by:

Q = C × m × ΔT

where:
Q is the heat absorbed or released by the substance,
C is the specific heat capacity of the substance,
m is the mass of the substance, and
ΔT is the change in temperature.

Step 2: Identify the given values

From the information provided, we know that the heat capacity (C) of the iron calorimeter is 68.85 kJ/°C. However, we don't have the values for Q or ΔT.

Step 3: Utilize the heat capacity formula

Since we don't have values for Q or ΔT, we cannot directly calculate the mass. The heat capacity alone does not provide enough information. We need additional data related to the change in temperature (ΔT) or the heat transfer (Q) to calculate the mass of the iron calorimeter accurately.

If you have any additional information related to the question, please provide it, so we can proceed with the calculation.
