Given the specific heat of lead is 0.129 J/g#*#K and that it takes 93.4 J of energy to heat a sample of lead from 22.3°C to 40.°C, how do you find the mass of the lead.?
The equation you want is
In the question, we want to find mass, so we rearrange to make mass the subject:
We know that
(We can easily convert between
Now we have
