Question

An unknown sample is being evaluated in lab. What is the specific heat capacity of the compound if it requires 266.98 J to raise the temperature of 57.46 grams of the unknown from 15.2 °C to 64.5 °C.

Answer 1

q = mC∆T

266.98 J = (57.46 g)(C)(49.3º)

C = 0.0942 J/gº = specific heat of the unknown
