742.5 J of energy is used to heat an unknown mass of aluminum from 10° C to 65.0° C. The specific heat capacity of aluminum = 0.90 J/(g·°C).
What is the mass of the aluminum?
3 answers
mass=heat/(specheat*deltatemp)=742.5J/(.9J/gC*55C)= 742.5/(.9*55) grams
Thats not correct
742.5/(.9*55) = 15
so it would be 15 grams
so it would be 15 grams
