Calculate the mass in grams for a gold sample that absorbs 225 to change its temperature from 16.0 to 36.0.
To calculate the mass of the gold sample, we need to use the equation:
q = mcΔT
where:
- q represents the heat energy absorbed (in joules)
- m represents the mass of the gold sample (in grams)
- c represents the specific heat capacity of gold (in J/g°C)
- ΔT represents the change in temperature (in °C)
First, we need to determine the amount of heat absorbed by the gold sample. This can be calculated using the equation:
q = mcΔT
where:
- q = 225 J (given)
- c = specific heat capacity of gold (look up the value)
Next, we rearrange the equation to solve for the mass (m):
m = q / cΔT
Substituting the known values, we have:
m = 225 J / (specific heat capacity of gold) * (36.0 °C - 16.0 °C)
You would need to look up the specific heat capacity of gold and plug it into the equation to get the final answer.
