An unknown substance has a mass of 28.1 g. The temperature of the substance increases by 16.3 degrees Celsius when 176 J of heat is added to the substance. What is the most likely identity of the substance? The table lists the specific heat capacities of select substances.

  • chemistry -

    q = mass x specific heat x delta T.
    176 J = 28.1 x specific heat x 16.3
    Solve for specific heat and compare with the table provided.
