1. The problem statement, all variables and given/known data
What is the maximum mass of ethyl alcohol you could boil with 1000J of heat, starting from 18∘C?
2. Relevant equations
Q=mcΔT
c ethyl alcohol = 2400 J/(kg*K)
T boil ethyl alcohol = 78 C = 351 K
T starting = 18 C = 291 K
3. The attempt at a solution
m=Q/(c*ΔT)
m= (2400 J)/[(2400 J/kg*K)(351 K -291 K)] = .00694 kg (or 6.94E-3 kg)
It tells me this is wrong. I am probably overlooking something quite obvious. Thanks :)
